Peter and the Shadow Thieves, by Dave Barry, Ridley Pearson

A fantastic sequel to "Peter and the Star Catchers." In fact, I liked it even better than the first book. In this story, Peter overhears a deadly plot of the Others to steal the starstuff back from Molly and her father. Knowing that they need to be warned, Peter attempts to fly to London, only to have to hide and seek refuge on the ship of the very men who are plotting the evil. The adventures continue as he reaches London and tries to save Molly and her family from the mysterious shadow thief.  I give it 5 stars and a PG rating.
