Despite those strikes against it, Between is highly engaging, and I credit Warman’s writing for that. Her language flows and she’s created a great character in Liz. She starts out like your stereotypical mean girl, but like in all good books, she grows (despite being dead). And we as readers see that she maybe she wasn’t so two-dimensional in the first place. People aren’t easy, they can’t be pigeonholed, and Liz is no different. In that respect, the book is as much an education for the reader as it is for Liz.
Warman is less successful with Alex. He is vital to the story, and he needs to be present to move the plot along, but that’s all he is: a device. I never felt like I knew Alex beyond his role as a clue for Liz. This is Liz’s story, so this fault doesn’t cripple the book entirely, but it does weaken its impact.
