The Trials of Lila Dalton: A Novel by L.J. Shepherd

I look up to find twelve strangers staring back at me. and I realize I'm the one they're waiting for.
Lila Dalton has no memory of how she came to be in this courtroom; no memory of how she got to the courthouse at all, or why she's facing a jury who seems to be waiting for her. The man on trial is accused of mass murder, and she's his lawyer, but she can't remember any details of the case. She can't remember anything. Stranded on an island in the Atlantic Ocean where the most serious crimes are tried, Lila has to prove her client's innocence if she wants to go home. But how can she solve this case when she's not sure she can trust anything around her, including her own memory?
The Trials of Lila Dalton is a twisty, unexpected locked-room mystery that follows one woman's race against time to find a killer, clear her own name, and escape the island that threatens to keep her trapped forever.
