Moon is a Raksura, a type of flying shapeshifter, who has a backstory of surviving on his own and not even knowing he was a Raksura until a line grandfather from the Indigo Cloud court found him and brought him to Indigo Cloud. That backstory is recounted in the previous book(s), which I haven't read yet. At the start of this book, Moon is settling in to Indigo Cloud as consort to Jade, sister queen of the court. He's still not feeling totally secure, and what security he does have gets a major blow when visitors arrive with the news that another court, Opal Night, is claiming him as the lost son of their dominant queen, Malachite, and wants him back immediately.
What follows is a wonderful exploration of a very interesting world, along with adventure, derring-do, and oh yes, Moon's personal trauma as he gets to know his birth family, tries to figure out if anyone (even Jade) is on his side, and finds out what really happened when he was separated from his family forty turns ago.
I honestly found this totally absorbing. Even though I didn't know background material that Wells assumes readers have already learned from the previous books didn't slow down my enjoyment much if at all. The Raksura are a fascinating creation, very enjoyable to get to know, and the characters are extremely well done, complex, interesting, and likable.
A great read. Recommended.
