I can't get enough of the SIGMA group, and Rollins delivers with BLOODLINE. Great to see Monk and Kat again, as well as bigger roles for Lisa and Painter. I wasn't sure about the relationship with Gray and Seichan when Rollins introduced it in DEVIL COLONY, but it was great to see it show up here again.

BLOODLINE is a thrill-ride from the very first quote on page 1, and keeps the twists, loops, and surprise twists coming right up to the very end. Fantastically written, well-developed, and entertaining.
