Where Shadows Dance — Vered Ehsani

Ash was looking forward to a summer of camping with friends and time travelling. Then his Great Aunt fades away (literally), his near-death nightmare gets even weirder and he keeps falling into someone else's dreams. On top of that, his house is attacked and he gets trapped in the past while trying to help a new friend who isn't too friendly. Juna isn't having a great time of it either: having escaped from her parole officer, she barely survives falling out of a plane and getting sucked into a bizarre tornado that keeps appearing in the most unlikely situations. While Ash and Juna try to get out of the past and back home, events and dreams keep pointing them to the place where it all starts and ends, where shadows dance and time bends. If they can get there, they may be able to stop an implacable enemy from destroying their future. Of course, getting there means surviving first.
