Team Leader Bear by Candace Ayers

With a hole in her heart, and a gnawing emptiness,
Hannah’s sworn off men.
That was before she ran into the Siberian hottie.
Just being near him quells the ache in her chest.
As the P.O.L.A.R. Team Leader, Serge is caught in a dilemma.
Either the mission continues, or he pursues his mate.
Not both.
The careers of his team hinge on this mission’s success.
But without his mate, his life is entirely meaningless.
