Tessa is a landscape architect, specializing in labyrinths. When she receives a phone call from an old friend/love requesting she join him on a special task, she reluctantly agrees to at least check out his offer. The project ends up being a unique labyrinth that she can't resist. So, she and the friend, Smith, end up working together...and possibly end up as more.
There's also a huge psychological aspect to the story. Tessa is haunted by nightmares of monsters and labyrinths. In a way, I was reminded of Susan Howatch's work (which is a compliment). There were deep-seated issues that she had to address and conquer in order to be a whole person again. Sometimes I did think she was a little crazy but it all works out in the end.
The story tied together nicely and yeah, creeped me out at parts. While this is labeled as Christian fiction, that shouldn't scare anyone away. It was part of the story and part of Tessa's healing, but there definitely was no preaching. And the labyrinth part was actually very interesting, too. I like learning about new topics and now I know a little bit more about mazes vs. labyrinths.
