Her Wish, His Command By Malia Mallory
This is a mild BDSM book. It is the third book in the series, but is ok to read by itself, but you will want to know what happens after the abrupt ending. I liked this book and will get the others to read too.
Anna and Jonah are researchers who work together. Anna has wanted Jonah since her internship. Jonah has kept things professional. The chemistry between them is great.
It is a well written story, great job Malia.
