Met My Dragon And Went Into Labor by Lorelei M. Hart

I was hit by a train and woke up in another world—one where I was famous!
I thought I hit the jackpot with my wolf mate. He is kind, protective, and exactly who I need in my life. And then one day—poof, I run into my bear mate, and the three of us make it work. I’m happier than I ever dreamed possible.
My life is exactly how it should be.
Fate disagrees and sends me Seymour, just in time to help deliver my baby. Now I have to balance my life as a father of a newborn while I begin my life with my new dragon mate, and keep the life I have with my wolf and bear from falling apart. Easy peasy… or more likely, the most difficult thing I’ve ever done.
