His Temporary Omega

When Evie was dying and needed $120,000 for treatment, I thought I was out of options.
Until Dr. Martinez offered me a "solution"—a temporary pairing contract with the Blackthorne family heir. Three days, $150,000, enough to save Evie's life with money to spare.
Caspian Blackthorne is the most powerful Alpha in the city, with wealth and influence beyond measure, while I'm just a single Omega mother running a failing diner on the edge of werewolf territory. We should exist in completely different worlds.
I prepared myself for everything, ready to fulfill every clause in that contract.
But what I didn't expect was this—when the heat accelerator kicked in, this untouchable Alpha actually refused. He'd rather sleep on the floor than lay a finger on me.
"When this is all over, I want to know that if you ever choose me, it's because you want to, not because you have to."
Wait... choose him?
What the hell is this man thinking? And when he starts showing up at my diner every day, helping Felix with math homework, listening to Ruby's school stories, taking care of sick Evie...
I realize I'm facing something far more dangerous than a $120,000 medical bill.
