My Untamed Beastmate

In a world that has already gone through its apocalypse, zombies are everywhere and the men who are left can turn into beastmen. The power comes with a risk, since a man who changes can lose his mind and go into a frenzy, and only a woman can calm him. Yvonne Smith ends up in this world by mistake. She had completed 100 missions and was due to be sent back to her home planet, but the system that handles the transfer sent her to the wrong place. She is now in the body of a daughter of the Duchess of Northreach. That daughter had five husbands, all of them beastmen and all of them highly regarded.
