After On Demon Wings, I was SO READY for Into the Hollow. After everything that comes to light during On Demon Wings (and then what we learn during the two novellas--Old Blood and The Dex-Files--between books 5 and 6), I had to know how it all played out. WHAT WILL HAPPEN? Dex! Perry! Dex and Perry! The ginger douchebag! Perry's parents! Her sister! Dun-dun-dun.Perry makes some big changes in her life--like moving out of her parents' house and going back to Experiment in Terror. Though where she moves and who she moves in with is worth noting, the bulk of this book deals with the latter--Experiment in Terror. Perry thinks searching for Bigfoot (major points to Karina Halle for getting in a mention of Bigfoot erotica) will be better and safer than hunting for ghosts. Oh, Perry. You'd really think she'd know better by now. But honestly, it's better that she doesn't otherwise...where's the fun in avoiding a little risk taking?So, this book. Into the Hollow is a book of moments. Funny moments. HILARIOUS moments. (Twatwaffle, anyone?) Awkward moments. Angry moments. Sexy moments. Swooning moments. (Dex really brings the swoon in this one. Karina brings teh sex. We're talking hot enough to melt snow.) And lots and lots of utterly terrifying moments. But honestly, it wouldn't be a Experiment in Terror book without being scared shitless. And being scared shitless is just part of the Experiment in Terror charm. It's good stuff.I really can't get enough of this series. I don't want it to end! The Experiment in Terror series has really awoken an interest in ghosts and the supernatural. And I love it.
