Veiled Eliminators Series by Taryn Jameson, Gabriella Bradley

Two is an eliminator, a trained assassin. She has one mission—enter the portal, eliminate a rogue general, then activate her microchip to wipe her memory. But she knows a secret that would rock the foundations of the Institute’s training program. Armed with only a tiny dagger, and the truth of their future, she enlists the help of her partner, Four, to escape their fate.

Her lifelong dream is of freedom, and she would risk everything to make it come true. When she is sent as a spy to a penal colony, aptly named New Alcatraz, her dreams of freedom take a nose-dive... moreDeath is the only means of escape on a mission to hell… Twelve knows only one life—the Institute.
