Fragments by Dan Wells, Book 2 in the Partials sequence, is expected for publication next month (February 26, 2013).
If you're getting impatient for the release, you can read the first 40 pages below.
Kira Walker has found the cure for RM, but the battle for the survival of humans and Partials is just beginning. Kira has left East Meadow in a desperate search for clues to who she is. That the Partials themselves hold the cure for RM in their blood cannot be a coincidence--it must be part of a larger plan, a plan that involves Kira, a plan that could save both races.
