I.S.S.: The Completed Series by M. Sinclair

I didn’t fear my nightmares. I loved them… and they loved me.

Join Arabella and her possessive monsters as one human woman finds the strength—and the monster within herself—to protect those she loves. Abandoned at the gates of the Institutum Sequuntur Somnia (I.S.S.), Arabella grew up among the creatures humanity fears most. With pink hair, a vision impairment, and a fearless, slightly naive heart, she becomes the unshakable anchor to a team of lethal Nightmares—from the monster under the bed to the overbearing son of Lucifer himself.

As Arabella unravels the mysteries of her past and the twisted secrets buried in I.S.S., she forges unbreakable bonds with her monstrous mates—men born of darkness and danger, yet hopelessly devoted to her. Their connection is fiery, forbidden, and full of heart-pounding steam. Together, they fight enemies from within the institute and beyond, challenging every rule meant to keep them apart.
