Lilith (Lilith #5)

Welp. Looks like the gooby creature wasn’t quite dead afterall, and now he’s found a new Priest-like skin-sack to walk around in. This just isn’t Lilith’s day. Stuck in the subway fighting this goob creature once again, Lilith learns that it’s made a few clones of itself. And they’re threatening Penelope and Ben at their shop! Now Lilith has no choice but to team up with Michael to take care of this pest problem. Wish there was something in the book that could help...
