Leviathan, Behemoth, and Goliath

A trilogy of books by Scott Westerfeld.  These are considered steam punk books and my first foray into the field of steam punk.  They are YA books but don't read too young.  I picked up Leviathan not realizing that it was a first in a series, I hate that.  I had to wait for each of them to come out.  Lucky you,  you can just go pick them all up.  Really, really fun and different.  Fast reads and fantastic artwork.  Thumbs up.
