I tidied my physical bookshelf yesterday, which means I’m able to answer this question 🙂
Freefall by Kristen Heitzmann
It has an amnesia plot (a favourite), a suspense element (another favourite), and it’s set in Hawai’i (my favourite US state). What’s not to like?
Here’s the book description:
When a young woman stumbles out of the Hanalei Mountains on the island of Kauai with no memory of who she is or how she got there, Cameron Pierce reluctantly agrees to investigate the mysterious circumstances surrounding her arrival. As pieces begin to fall into place, he suspects her injuries were no accident, but he’s far from convinced she’s an innocent victim. And there’s that nagging feeling he’s seen her somewhere before …
Now known as Jade, the woman begins to recall fragments of what led her to this place, and she realizes the danger isn’t over. Jade and the cynical Hawaiian investigator attempt to reconstruct the threads of her identity, but the stakes are far higher than either expected.
Words by Ginny L. Yttrup. She also has quite a few one-word titles 🙂
