Rainbow's Storm (The Billionaire's Betasitter Book 4)

Revenge is a dish best served in a bikini.
Rainbow
Five years ago, billionaire/thirst trap Storm Halder walked into my life, rejected me as his soulmate, and walked away. That same weekend, my stepdad left Mom and me with nothing but a leaky roof and a stack of bills.
Before that day, my name was Rainbow. Now, it’s just Rain.
Am I bitter? Heck yes. But when I take an unusually lucrative betasitter gig and end up inside Storm’s mansion, I finally have the chance for revenge.
So why are my plans to get payback turning into fantasies about kisses in the rain?
And why does this jerk’s groveling make my heart thunder?
Storm
Five years ago, I met my far-too-young true mate, and gave her up to save us both. Now Rainbow’s at my front door, claiming to be the betasitter hired to help with my foster son, and I have a second chance…to grovel for forgiveness.
Having her in my home, wearing tiny bikinis and putting me in my place, is a punishment I only imagined in my wildest fantasies. Rainbow will get her revenge, but if she asks for more? I may have to reject her again to protect her from what’s coming.
Because there’s no rainbow at the end of this storm.
