I mostly read this because I really miss BatB, and it was pretty much what I expected.
It's not a /bad/ plot, and the characterization, of Cat and Tess mostly, is pretty good. The romance and fade to black sex scenes were cheesy, the part with Celest and Gabe seemed just kind of shoved in there and well actually the whole thing was pretty cheesy, not in the best way.
I was excited that Gabe is in it, but oh my god he is not some supervillian. "Planning his plans, and scheming his schemes," like really? Maybe I'm biased, and I mean on the show for the last four episodes of the second season they changed him so badly, but like damn.
Not to mention there was one plot point from Gabe's POV that I feel like i must have missed but I'm 99% sure just was never explained...
It's fun to complain about, and I'm most likely going to read the second one, but it's only worth it if you're like me, and really really love and miss BatB.
