His to Take by Summer Cooper

Ann is alive. So is Rex.
She’ll be forever grateful for her father’s bunker.
They would never have made it otherwise.
There might only be one man her age left in this world…
And she’s lucky that it was Rex.
Her high school crush, the man she’s loved for such a long time.
She couldn’t help but giggle at the thought that they might have to repopulate the human race.
The thing is, Rex isn’t completely human anymore.
Her sweet Rex has an animal side now – a wolf side.
He can be dangerous, vicious, violent.
Ann wants to love him, unconditionally.
Besides, who else could love her back?
Then he came to her, in her dreams… the man with the orange eyes.
