A review by jamelchior
Yesternight by Cat Winters

I received an advance copy of this book from a Goodreads giveaway. The story might be about ghosts, reincarnation or possession. It's authentically creepy in the way a Sherlock Holmes story is creepy, with the important difference that Holmes always succeeds in explaining apparently supernatural happenings in scientific terms, and in Yesternight a narrator who's trying hard to be scientific in the end has to accept spiritual realities and a certain level of continued mystery.

I was delighted by the post-WWI setting, and especially the difficulty, slowness and difference in quality of communication by letter, telegram and very occasionally telephone. The picture of the state of the art in school psychology and intelligence testing, is fascinating. These details hold our attention while an elegantly spare plot line slowly unfolds. And I loved having a young female mathematical genius in the story - or are there two of them?
