She wasn’t supposed to want them both. They weren’t supposed to let her.

Mila Carter has spent her whole life being the calm one, the easy one, the one who never asks for too much. When her best friend’s destination wedding strands her in a beach house with two of the groomsmen — a brooding firefighter who flinches at tenderness and a reckless musician who performs happiness like a second job — she’s supposed to keep the peace.

Instead, she lights the fuse.

Drew is silent where Rafe is loud. Drew holds back while Rafe crashes forward. They shouldn’t work together. They definitely shouldn’t work with her between them.

But late nights on the porch turn into early mornings in the kitchen, and stolen glances turn into stolen touches, and Mila stops asking herself who she’s supposed to choose — and starts asking herself what she actually wants.

The answer? Everything.

Frequently Asked Questions

Is this a love triangle?

No. This is an MFM romance where the heroine is in a relationship with both men simultaneously. The two heroes are not romantically involved with each other — their bond is brotherhood, not attraction. Mila is the center of the relationship, and both men choose her (and each other, as family) willingly.

How spicy is this book?

Inferno-level. This book contains multiple graphic sex scenes including solo encounters with each hero and full MFM threesome scenes. The heat is emotionally driven — every scene advances the characters’ arcs and the relationship. Expect explicit language, dirty talk, and scenes that will require a cold shower.

Is there a happily ever after?

Absolutely. All three main characters get their HEA — together, in the same house, with a life they’ve designed from scratch. No cliffhangers, no choosing, no one left out.

Do I need to read any other books first?

No. Built to Hold You Both is a complete standalone with no series connections required.
