Freeze Tag (Vintage Paperback) by Caroline B. Cooney

From best-selling author Caroline Cooney comes this suspenseful story of Meghan, whose relationship with her perfect boyfriend is destroyed by a girl who can freeze people with a touch of her finger.

When Meghan and West first played Freeze Tag with Lannie, it was no ordinary game. Because when Lannie tagged someone, they really froze. Icy blue and cold. Like death.

Now Meghan, West, and Lannie are in high school, and Meghan and West are in love. They're the perfect couple. But Lannie is determined to have West for her very own... and if she doesn't get her way, she'll freeze Meghan... to death.
