The first story in Mark Arbour's ongoing CAP series is all about JP and introduces some of the early cast in this ongoing saga. This is the foundation on which the whole saga in its many twists and turns is based.
Mark's story is what brought me to GA in the first place and his stories continue to be the most compelling for me as must reads! The whole saga which now encompasses some 16 books may seem overwhelming, but trust me they are reads you cannot put down and keep drawing you in to see more.
On a personal note, I am a contemporary of JP and Mark puts JP's story in the context of a history I share and so it is especially rewarding for me. So given that caveat, I may be unfairly biased a bit, but notice how many followers and comments are made on the stories and you soon see that he has a host of fans.
Take heed and read! CAP is the beginning of the whole series!
