Academy for Reapers, Year Two by M Guida

I fought my way out of Hell, but that’s not my hardest task. It’s winning the heart of a stubborn reaper.
He doesn’t need anybody. He doesn’t want anybody. He wants to be left alone.
He’s a wounded hero on the path of destruction.
He’s told me to get lost, but I’m not going anywhere.
An archangel has accused him of serious crimes at Soul Academy and has set a bounty on his head. I’m the only one who can heal my reaper’s broken heart, but I need a team to save him from his enemies.
The lines have been drawn. Bring it on. I’m ready to fight for my mate.
Come rally behind me in helping my dark and broody reaper realize he’s worthy of love.
