Reclaimed (Knights Rebels MC #2.5) by River Savage
This novella takes place after the first two books. The main characters are Kadence and Nix. The story starts with Kadence sharing the news of her pregnancy with Nix. Then, the story jumps to after the delivery. Kadence is dealing with postpartum depression. She's trying to adjust to being a mother, dealing with the new changes in her body and with a baby having problems feeding.
I'm glad the author picked to write about an important topic. The story is short and by the end it gives you a sense of resolution. It also gives you an idea of what's to come in the next book.
