The Underground by Lexi Ostrow

Trinity Jane knew no other life than one on the run. Her parents found her in a dumpster as a child and took her into their chaotic lifestyle as the leaders of a resistance movement to return balance and acceptance back to a world torn apart. She was human, but raised to believe co-existence through large-scale violence was the way to win the war. One day, she would take over the resistance, and she would lead the world into its next era.

Andre ha loved Trinity since they were teens. He’d sworn to stand by her side at all costs. Wielding control over air, he’s by her side as she descends into the depths to create an alliance. Nothing mattered except stopping the war around them, because he refused to raise a family in the hellish world they were in.
Sampson liked very little about the vicious way the world turned. He might be a wolf, but he longed for a life where he could spend his days on the waves as he had before the chip. When a human forces her way into his tunnels, he’s not only attracted to her looks, but the plan she offers.

Viktor hated life in the shadows – hated the blood he needed to survive even more. He was only a vampire thanks to his family’s wealth and a stash of illegal chips. As the current ruler of the New York City nest, he held more power in a single word than most people alive. Power he would trade in a heartbeat for the human woman he’d encountered five years ago to return to him.
Amidst the chaos, a complex web of relationships forms within the resistance, transcending the conventional bonds of romance. Trinity finds herself at the center of a burgeoning harem, as she forms deep connections with the enigmatic members of the Shadow Guard. Their shared destiny intertwines their fates, leads to a passionate alliance, and a heart breaking betrayal as they seek to destroy the underground.
