Undeniably Forbidden: A Single Dad, Nanny, age-gap Romance (Boston’s Irresistible Billionaires Book 2)

Why we recommend it

A single-dad billionaire and the nanny he should keep his hands off — this one trades brutality for slow-burning forbidden tension. Expect protective alpha energy, an age gap that crackles, and the delicious wrongness of falling for someone strictly off-limits. Lighter on the darkness, heavier on the longing, it's a warm pick for readers who like their forbidden romance possessive but tender.
