Technically, You Started It
In Haley's school there are two boys named Martin Nathaniel Munroe II (it's a long story). So when one of them texts her about a history assignment, she asks which one she is talking to. The response, "The good one" leads to a case of mistaken identity.
This book has a unique format in that it is told entirely as text messages with lots of cute twists and turns. It is a lighthearted teen novel that I thoroughly enjoyed and highly recommend!
