Jack and the Giant Killer is book 4 in the Jack Stratton series. For those new to the series listen to book 6, And Then She Was Gone, first. It is not as good as the others but it does provide helpful background. Then move on to Girl Jacked and read the rest in order. The protagonist is Jack Stratton, but the co-protagonist, a girl named Alice but called by her nickname Replacement, is the most interesting character in the series. Book 5 has not yet been released in audio, but I hope it will be soon. Also, author Christopher Greyson should continue the series with book 7. The novels in this series have intense suspense, are fast paced and are fun. The Jack Stratton series deserves a larger audio audience than it currently has (the Kindle audience for the series is much larger).
This suspense mystery series is so good that I regret being limited to 5 stars in rating it. The narration of Andrew Tell is is good as the novels.
