The Coincidence Of Kallie And Kayden is the story of two college students who meet and eventually fall in love. Kallie is a drab girl with a secret in her past. Kayden suffers from beatings by his father and self injury from himself. The two friends are well developed and likable. Seth being Kallie’s gay best friend and Luke Kayden’s hulking jock best friend. I felt the mysteries of the two lead characters should have come out earlier in the book. And I don’t understand why there was no ending. The story just stops. I have since learned that there is a sequel planned but I still would have liked some sort of ending. That aside, I would still recommend this book especially to young adults.
