Jack of Hearts is Book 7 in the Jack Stratton series. It has become one of favorite series and Christopher Greyson has become one of my favorite authors since the audio versions of some of the novels were first released five months ago. The series dwells in the light and fun part of the mystery/thriller genre. The novels also have more romance, but not sex, than most written by male authors. Author Greyson writes about some sympathetic but flawed main characters and he develops them brilliantly. The main characters are ex-cop Jack and his girlfriend Alice (Alice is not called Replacement for the first time in Jack of Hearts).
I love the Jack Stratton series and I highly recommend it. The books do not have to be listened to in order; indeed, Book 6 titled And Then She Was Gone should be read first followed by Book 1 titled Girl Jacked followed by Books 2, 3, 4 ,5 and then 7. Andrew Tell narrates all books in the series superbly.
