The Caring Omega (The Omega Pack #4)
Rose Penny

Silas is a widowed omega that loves taking care of others. He’s scented his fated mate, but doesn’t know who it was.
Topher is an alpha who’s always working. He has no time or desire to take a mate. What will he do when his fated mate comes to him looking for a job?
The Caring Omega is the fourth book, a novella really, in The Omega Pack series. It is a sweet, low to no angst, non-shifter, m/m, omegaverse mpreg romance novel. It can be read as a standalone and does have a happily ever after - no cliffhangers.
