The Hollow Oak by Stockton Smith *signed*

When Jessica Lin, a college student and turbo nerd, is kidnapped by a local UFO cult, it's serendipitous that her mother hires Cass and Artie to bring her back.

Professionally speaking, they've been in a dry spell for months. The only people hiring want pro bono work. Maybe Cass was right, and all they needed to do was manifest the Golden Case.

Turns out everyone's looking for Jessica. The only way to rescue her is to infiltrate the cult's compound, figure out who's really in charge, and do battle with a foe who may or may not be human.

What Artie doesn't know is that for Cass, this is personal...

The clock is ticking. Will they find Jessica and escape? Or find themselves a little too happy in their new community?
