The books in the series:
1. The Dangerous Days of Daniel X by James Patterson and Michael Ledwidge.
2. Daniel X: Watch the Skies by James Patterson and Ned Rust.
3. Demons & Druids (Coming Out: July 26, 2010)
I have read the two books currently out,
and they've been, overall, good and enjoyable...
But, really, Maximum Ride tops it by a lot.
