Flint's Arrow. Assassin's Alley, #4

"...he took one look at us and decided we weren't assassin enough, weren't alpha enough, weren't enough full fucking stop..."Flint, snake shifter and the best sniper on the Agency's books, met his mate while he was in the middle of a job. Unfortunately, when the wolf shifter opened his mouth all of Flint's fears came true, and showing a lot more strength than he believed he had, Flint left, did his job, and walked away.
But the Fates don't like it when their matings plans don't work out, and Flint is feeling the separation deeply... he only hopes Arrow is feeling the same way. I made a mistake, but I can't fix it if I can't find him. Arrow, wolf shifter, who works in the Cybercrimes unit of the same Agency Flint works for, met his mate, opened his mouth and shit came out. He knows it. He regrets every second of it.
But unfortunately, as far as first impressions went, he'd made a mess of it and he couldn't even find the cute blond assassin, let alone try and get a second chance. He's using his actions, not words, Flint realized. He's showing me, not just telling me, that he can change. That's a freakingly big change. That mating pull is strong, and of course, Arrow and Flint need to meet up again, but it's not an easy path.
Arrow has to make some big changes to get Flint to even give him a chance, and when other people decide that maybe the bond between Flint and Arrow isn't a true one, they add their own brand of pressure to an already volatile situation. Flint's Arrow can be read as a standalone, although reading the previous books will give you a better idea of the secondary characters who play a big part in this story.
The book does finish with an HEA, and the Epilogue leads into the next and final book of the series which will be out later this year.
