REVIEW :

1. Cover, Title, Summary (8/10)
Cover is very attractive, and the quotes+text (other than title) on the cover image make it more appealing. The color contrast is excellent and the quotes are touchy, as well as, curiosity invoking. However, the background image can be more pronounced/changed, as it's (the image of couple) not clearly comprehendible.
The title basically depicts any one of the many elements related to the book, eg.- the theme/ characters' motive/ gist of the plot / genre etc. Your book's title relates very appropriately to the storyline and theme of story.
Summary is attractive & very well written, just pay attention to the few mistakes (punctuation, spacing).

2. Images/photos etc., audio, video, GIFs- Graphics (8/10)
Images- cover photo, and some other couple photos. Some photos with the attires of characters are also attached, which are relevant and thus add to the interest development in readers. Photos of plants, flowers, Niligiri Hills (where those plants grow), are also attached and all are relevant (female character is a, to be botanist). A GIF of a dancing couple is also attached.
All the images+ 1 GIF used, suit the character description as well as the storyline, and other graphics aren't needed.

3. Grammar, Spelling, vocabulary (4/10)
Spelling mistakes- few, in the starting six chapters
Grammar: Punctuation - comma, single & double quotation marks mistakes, period placement, spacing, are present, at many places.
The placement of defining & non defining clauses, with determiner placement also need editing in chapters.
Word mistakes - I couldn't observe any.
Word repetitions are present (eg- that used twice in the first paragraph of first chapter) and can be reduced.
Vocabulary is kept simple, but appropriate and good for acquainting the reader well with the story.
Some sentence formation mistakes are present too. At some places, only the rotation and shuffling of words here and there, in a sentence, will be sufficient, to correct them.

4. Literary elements: plot, setting, characterization, conflicts, POVs, mood, tone (8/10)
The plot/storyline is a teen fiction romance+tragedy and drama.
Settings (meaning living environment, clothing, conversation styles, food habits, Transportation, etc., as per the time & place cited in story) are very well described, though still need some more clarification. None of them are explained separately, in a boring manner, rather, they are spun with the progressive events, which makes it interesting to read.
Characters are developed gradually & very effectively with the development of their school & personal lives, simultaneously.
Conflicts are all cliche, but still very well woven with the story (since it's inspired by a true incident, which seems cliche, in general, to most readers.)
The book is written in first person  POV and author wrote it adequately with respect to teen behavior in some places, and as a grown up mature adult in other places. The thought process of both the stages is linked very well too.
Since the story flickers between past and present continuously, moods and tones are varied at points.
Moods (these are the emotions aroused in the reader by the write up) induced are variety, depending on the event description- cheerful, light hearted (merry scenes), depressing, uplifting, hormonal too (in case of mature scenes) etc. Tones (meaning author's attitude) are jovial, carefree, mirthful, humorous, sad, violent etc. I must say that the tones, moods and POV, are effectively presented, in spite of the story spinning in between present and past flashbacks.
Author has clearly given warning notes, in bold letters, before a mature scene, which is very good.

5. Diction, writing style, pacing (8/10)
Diction is good, with a nice & fitting choice of words, but at some places the choice of adjectives, nouns, adverbs need replacement for providing the reader a good imagination (called imagery). Since the story scenes rotate very frequently from present to flashback, and vice-versa, a slight lack of word usage seems pronounced.
Writing style is informal narrative, but written very well. The story telling is very good (it's not easy to write and link various facts/figures/incidents between the present and the past).
Pacing is kept moderate and fits with the pace of events/incidents spun in the story. However, at some places pacing seems fast, but it's enjoyable and relatable. Prologue, introduction etc are not present, but the storytelling doesn't suffer from it.

6. Allusion, epigraphs, euphemism, foreshadowing, metaphors/simile, imagery (6/10)
Foreshadowing is used, very effectively. Every chapter unfolds information gradually, of the present situation the characters are facing, and their past occurrences. Author excelled in maintaining the necessary suspense, and keeping the readers bound.
Author tried to use imagery, in the mature intimate scenes and to a quite good extent, they leave their imprint; though author has kept them light and less intense, so I think readers will like it.
Other devices not used, which may be due to the story requirements.

7. Structuring (8/10)
Starting & ending clearly presented in text. Paragraphs, dialogues are presented in a good manner. Chapter names are precisely chosen according to the content. Chapters are numbered, which gives it a professional outlook & is convenient for a reader to read and continue, where he/she left last time.
Book structure- doesn't contain introduction, prologue, cast etc., but I believe that's not required (Author has described everything very intriguingly and no other parts are needed).

8. Cliffhangers, twists/turns/incident presentation (8/10)
Cliffhangers are excellent and, the concept of story, inspired by a real incident, is attractively presented, which draws the reader in.
Twists and turns are many and are disclosed gradually, with each chapter, which keeps the reader bound.
Very well done.

9. Originality, creativity (5/10)
The story has many cliches, but still it's an interesting subject and the curiosity to know how the author has presented the tragedy which happened on 'that unfortunate night'. No doubt, every author has a new and different way of telling things, which is observed here too; it still doesn't count towards Originality.
But, the author has presented everything very creatively, and differently.

Rating/Marks :
8+8+4+8+8+8+8+8+5= 65/90

Reviewer's note:
The story is very interestingly spun around the various amusing events/incidents. Very interestingly put.
The story continuously revolves around the present scenes and the past flashbacks, and the way they are linked, is intriguing, making the readers curious, to explore further.

ADVICE (to author):
I have already mentioned some suggestions above, if the author would like to consider. Nothing more is required.
I am impressed by the way, the book keeps readers at edge, all the time and I congratulate the author for that.

If there is anything you don't understand, let me know, as an inline comment here. I will surely explain, if I find time for it.
