Second in The Mysterious Mr. Spines
series, it continues Edward's adventures as he discovers his abilities as the son of a Guardian (read: Angel)and struggles to save his mother from the clutches of the Jackal. He does not get very far, but he does make new friends in Tabitha, a young Guardian, and Bridgette, a young girl trapped in a coma on Earth. After treating his father harshly, Edward comes to terms with his choices and after his father is also captured by the Jackal (at which point Aunt Augusta's words were ringing in my ears:"To lose one parent may be regarded as a misfortune. To lose both looks like carelessness."
), he is doubly determined to rescue both his parents, though that is of course what the Jackal is counting on. Cue evil laughter.
Again, these books lack a depth to the storytelling which really stifles the story and the characters.
Kids 7/8 and up and it would appeal to boys.
