Book 6. To Blunt The Sharpest Claw
The third book in the Morrigan Trilogy.
As this book hasn't been written yet, there's not much that can said about it, other than it's due at the end of 2018 and will have excellent spelling.
When things become far worse than anyone anticipates, Oscar is forced to do things he hasn't been trained for. And even if he had been, he'd still be reluctant for involvement. In a suspense-filled climax that rivals far better books, a cast of hundreds comes together for the sort of finale that leaves readers questioning not only themselves and the author, but the purpose of punctuation.
