Axel by Callie Rhodes

There was only one place she left for her to run…straight into the arms of a monster.
The beta world is changing. Fears over rogue alpha attacks have peaked, and so has the public’s suspicion of anyone that has a connection to the Boundarylands. So when Maggie Harrington refuses to publicly disavow her alpha brother, she isn’t just disowned by her wealthy parents and cast out of her community—she’s also threatened by mysterious government agents who demand her compliance…or else
As hellish as his years of imprisonment were, Axel is finding it hard to adapt to life outside his solitary cell. In the escape, he may have found freedom, but peace still eludes him. At least until a woman fleeing the same people that locked him away trespasses onto his property. She may have come from the outside world, but Axel can tell at first glance she’s no beta.
She’s an omega…and that makes her his.
Once there were boundaries…but now that their chains are broken, these alphas refused to be contained.
