3rd Person POV

A monotone blur darted through the trees, a black blur following on the ground. The snow blew around, swirling as the wind pushed it around. Percy liked it here, everything was free, uncontrollable, just like him. He whistled a high note to Mrs. O'Leary, sending her a signal, they had been working on this trick for a while now and this was the test run.
Percy sped up, almost breaking the sound barrier, it shouldn't have been possible but Percy had spent fours years out here - training, honing in his skills - pushing himself and his Hellhound past the limit, facing bad results as well as good.
Percy gradually pulled ahead of Mrs. O'Leary and he pulled his ice staff from his back.
His ice staff looked similar to the one he saw in a movie, he couldn't remember what the movie was called but he remembered the practical uses of the staff, the curved hook for pulling and the length for thwacking  people. Okay, maybe that last one wasn't in the movie but it sounded cool. Percy had copied the design, but with prominent changes. For starters, his was made of ice and it was wood in the movie, the movie one was the dudes power source and his is a weapon and a way to look after Anaklusmos without loosing it - it was also cool for swinging on tree branches with - and lastly, the dude in the movie's is blunt on both ends and not that dangerous whereas Percy's has a few dozen lethal spikes on one end.
Back to the present, Mrs. O'Leary barked at Percy, saying she was ready. Mrs. O'Leary had grown in size since they escaped to Alaska, she was more than seven foot tall and was as wide as a NY taxi cab.
Percy jumped, swinging himself in a circle on a high branch, becoming visible above the tree line for a brief moment before sinking below again, into the cold of the forest. His legs latched onto a branch by the knee, his frozen staff dangling below him (see picture at top for better detail), as Mrs. O'Leary stampeded towards him. Mrs. O'Leary's head connected with his chest, flipping him around so his legs unlatched and he fell on Mrs. O'Leary, landing so he was sat the same way a person would on a horse. Mrs. O'Leary and Percy let out sounds of joy, one a bark and the other a whoop.
They shadow travelled away, neither of them noticing how they had crossed into Canada for a few seconds.

Into the gods domain.
