Winds of War by H.M. Wolfe

After spending almost two years in prison, as an informant for the special prosecutor Ian Saint-Clair, Seamus MacAtee comes back to The Base, the place he came to call home. He brings with him Kieran, his cellmate, who is welcomed with opened arms by some of the residents. Teaming up with Spyros and Van, Seamus leaves the next day, on an important secret mission.
Montemayor begins his little dirty war games again. The drug cartel boss’s advisor, Lauren Briggs, uses lies and deceit to convince other gangsters to join Montemayor, but the mobster’s decision to take two boys under his wing puts her loyalty to test.
At The Base, a strong alliance is reinforced and a new love blooms, but a mysterious outsider intervenes in the game, threatening to tip the balance in Montemayor’s favor. Will this new player change his mind and side with Ardan, or will he destroy The Base and everything the men behind it worked so hard for?
