Author Jonathan Green brings is an adventure of the Doctor, Amy, and Rory as they land on a tramp steamer heading for Florida. The Venture, the tramp steamer in which they landed on is on a quest for the fountain of youth. The Doctor being a Time Lord and one who can regenerate every cell in his body isn't really interested in looking for the fountain but for the cause of the temporal anomalies that caused the TARDIS to come out of the time vortex in the late nineteenth century. Along the way they are attacked by a large prehistoric beast that nearly rips the Venture in two. Once they reach Florida, the Doctor is split up from Amy and Rory who are chased by a T-Rex. This is a great book and the twist ending is one to look out for but I highly recommend this book to all Doctor Who and science fiction fans.
