This book is a sequel to Patterson’s "When The Wind Blows" in which he introduces the six genetically altered children that can fly while still maintaining their human traits while equiped with wings. In this novel the children are back and they are involved in an adventure that could cost them their lives. Their adventure involves a mad doctor that wants to use the children in a project in order to fulfill his desire to preserve eternal life but, only for a few very afluent males.. In the first book the children are rescued by an FBI agent and a veterinarian. The rescue forms a close bond between the children and their human rescuers. The bond is so strong that the children want the two rescuers to be their foster parents. This involves them in a legal custody battle with their biological parents. Yes, the children do have human biological parents. They were kidnapped and genetically altered becoming part human and part bird. The six children are very close to each other and travel in a flock as birds do. However, their human traits are also present and an important part of their being. This book is very different from the usual James Patterson murder mysteries because it smacks heavily of science fiction. The flying children and their human and bird anatomy are very believable. His scientific research is well done. Patterson assimilates mystery and science fiction well and makes this a most interesting novel. Throughout the novel I kept asking myself “where is Patterson going with this?” As I kept reading I could almost hear Patterson saying “Follow me closely and I will show you where this is going.” It was worth it. The book is a great read. If you need a change The Lake House by James Patterson will fill that need.
