Every Other Day by Jennifer Lynn Barnes
"Every other day, Kali D'Angelo is a normal sixteen-year-old girl. She goes to public high school. She attends pep rallies. She's human.
And then every day in between . . . She's something else entirely."
Very intriguing introduction to this book. It was a fast read for me because it was hard to put down. Kali risked her live to save a girl she barely knows, a girl who can see the future befriends her, and the three are off to solve a mystery. All the makings of a very good teen read.
