1. Don’t sleep with the students
2. Don’t sleep with a patient
3. Stay away from Harold Astor’s granddaughter

Seems easy, right?

It was. Right until Amara Astor walks into his office with one of her own inventions – an adult toy – stuck inside her.

She’s a patient, a PhD student, and she’s Harold Astor’s granddaughter. She’s entirely off-limits.

Getting involved with her puts his promising future at risk, yet he can’t turn her away. Not when doing so means she’ll find someone else to test her crazy inventions with.

Author’s Note: This is a standalone romance with a guaranteed HEA.
