This story is unique, in that it is written in second person narrative, as a letter from Gemma to her kidnapper. Since second person is rare in fiction, it did, upon occasion, jolt my brain, and I’d have to reset to keep reading.
However, I enjoyed the story overall and thought it was well-written. Nothing really worked out the way I thought or expected. It’s a bit intense, in a weird and twisty sort of way, and it’s basically never fun or lighthearted. So don’t expect that. Expect unusual with a sad undertone.
