The first few chapters I thought, "why is this girl letting the men in her life push her to do things she obviously doesn't want to do" but as the book went on I began to think that maybe Ms. Homer really did (does) want to do all these wilderness things - she just doesn't think she does. I liked the interspersing of earlier adventures with the main Iditarod race. I think Ms. Homer did a great job of capturing the mental ups and downs that many endurance athletes face. Overall I quite enjoyed the book, though my electronic copy could have used a better copy editor.
This was an entertaining read and the characters felt pretty true to life, especially the way that Ginny deals with her life and the reasons that she and her boyfriend break up. The relationship of Ginny and her friends was a nice one and it was rewarding to see Ginny get her life together. My only complaint was the amount of cursing.
Ms. Ward takes a common theme - amnesia and a dark secret - and gives it a twist with human replication. Fiona doesn't know who she is, or even what she is. Ms. Ward maintains an atmosphere suspense where the reader is never quite sure who the "bad guys" are. An entertaining read.
