The Space Between Us (Electronic book text)

From the author of "Virtuosity," a novel about two sisters and the secrets they tell, the secrets they keep--and the secret that could tear them apart.
Amelia is used to being upstaged by her charismatic younger sister, Charly. She doesn't mind, mostly, that it always falls to her to cover for Charly's crazy, impulsive antics. But one night, Charly's thoughtlessness goes way too far, and she lands both sisters in serious trouble.
Amelia's not sure she can forgive Charly this time, and not sure she wants to...but forgiveness is beside the point. Because Charly is also hiding a terrible secret, and the truth just might tear them apart forever.
