Review

Perfection!

Sab is gooey good, with his daughter and how much he loves her, and his personal struggles, which make me love him more. Because he’s fought to be where and who he is. Not to mention his relationship with his brother and brother-in-law is so touching.

Finding Galen is the one thing he never knew he needed. This gorgeous man, who’s been through hell over the past couple of years after a fire callout gone wrong. He’s bold enough to draw out the inexperienced Sab, but in need of someone to love him too.

These two are special. Pure and simple.

Synopsis

When single dad Sab Dubois downloads a swingers app, it’s meant to be a bit of harmless curiosity—until his gorgeous neighbour catches him in the act and makes him an offer he can’t refuse.

Galen McCarthy, the firefighter over the back fence, doesn’t do love or relationships—and he certainly doesn’t do forever. Coaching his flustered neighbour through some first-time exploration seems easy enough.

No strings. No expectations.

No hearts on the line.

But when fate has Galen fighting for his life for the third Christmas running, everything he didn’t know he wanted comes rushing into focus—the man who fed and healed him, the little lady he adores, and the family he never knew he needed.

Because love doesn’t ask permission.

It steals your heart and wraps it in fairy lights.

It forgives your fears and guides you home…

To Christmas on Cosmic Avenue.

Christmas on Cosmic Avenue is a medium-spice, emotional MM romance about first times, found family, and finding your way home—just in time for Christmas.

Expect: neighbours-to-lovers, first times/sexual discovery, single dad × wounded firefighter, angst, addiction recovery/healing, found family, and the most perfect Christmas happily ever after.
