Both Omega Quadrant short stories in one volume...

Unexpected Heat, Omega Quadrant, Book 1.5 

Gray and Rohan Parker have been through one hell of a year. A mating that started out with both life and death, they’ve held on tight to one another for months, just trying to survive. Needing some alone time, Rohan plans a lavish vacation to paradise for Gray’s next heat - the honeymoon they weren’t able to take. Now that their twins are 15 months, they hope to finally connect again and share an intimacy they haven’t been able to since the toddlers were made.

But a mix-up with the bags threatens their little piece of paradise and brings up old fears and buried emotions. They face up to the loss, the love, and their future together - and have to decide if they let nature take its course. 

This sequel short story follows His Surrogate Omega. It is strongly suggested to listen to that title beforehand to avoid spoilers.  

Suddenly His Alpha, Omega Quadrant, Book 1.9 

Tulla has spent the last eight years in the Omega Quadrant, trying his damnedest not to get suckered into a mating. He has an independent streak a mile wide, but without many opportunities for omegas, he struggles to forge a path of his own. When his parents put their foot down and demand he attend an Omega Ball and hunt for his alpha, he goes, but under duress. 

While there, he runs into an alpha from his past who just might be his future, too.
