 Since the emergence of the Scorpius bacterium that wiped out the majority of the population, Greyson Storm has successfully led a group of men, known as the Mercenaries, through this tumultuous time. Everyone knows that the country's resources are beginning to dwindle, so in preparation for the future, Grey kidnaps Maureen Shadow, a renowned Bio Engineer, in hopes that she can help figure out the problem with the dying crops. What neither is looking for in this time of uncertainty is an attachment, but that's exactly what they find in one another. 
 After a drunken night of sex leaves Maureen pregnant, Greyson will do anything to ensure her, and the baby's, survival, even if it means forsaking the tentative truce between the Mercs and Vanguard, and allying himself with the President. 
 I liked that Storm Gathering takes us away from the Vanguard/Jax Mercury territory that has occupied this series for the first three books. It was interesting to get a different perspective from a different group who is just trying to survive in this crazy new world, just like the people of Vanguard are trying to survive. 
 Rebecca Zanetti really does a great job of taking Greyson Storm and using his character as a way to show the internal conflict that occur alongside the external conflicts imposed by the dystopian state of the world after the virus. It's also interesting because after having been in Vanguard territory, so to speak, for the last three books, as a reader it's difficult to imagine Grey not immediately aligning himself with the group that we've come to know and love. But when you look at the basics of the situation he finds himself in (trying to protect his unborn child when no child has been born post Scorpius Syndrome thus far), you see why he gives pause. 
 I liked the relationship between Maureen and Grey just fine. Honestly, I almost liked seeing them more in the secondary role in previous books because I could just feel the attraction jumping off the page more so there than I could once they moved to be the front and center couple. Also, Grey's alpha protectiveness was bordering on too much for my tastes (and this is before he finds out Maureen is pregnant). 
 One thing I noticed more in this book, and which I hope continues in books to come, is the female bonding going on. I mean we are four books into this series, and we have strong, smart, and capable heroines standing next to our heroes. I want to see this group of women grow and form their own "squad" (I know, I'm sorry) apart from the very testosterone-filled antics of the men. 
 Overall, I'm enjoying how Rebecca Zanetti is crafting this series. With each story we inch along the path to where we need to end up in the long run, and while she succinctly points out the issues our group(s) still have to deal with, I'm very interested in seeing how all storylines for our current characters continue while paving the way for more additions to the group down the line.
