I love the premise of this book: youngest FBI BAU profiler gets thrown back in time and must solve a murder – a serial killer! – through knowledge she personally remembers, without databases or other tools.
Skimmed through pages 1 to ~70, which is all covered in the back-cover text. Then, time travel! And the super-smart daughter of rich folks now has to deal with people assuming she is a stupid servant, and not a very good one at that. Stupid, low class, and prone to theft.
The world building is pretty good, the characterization is not, and I could not finish the book. Sigh.
