ACRO Books in Order

ACRO is the series Larissa Ione wrote with Stephanie Tyler under the pen name Sydney Croft, and it has a very different flavor from Demonica. These books are paranormal romantic suspense with a spy-thriller streak. The name comes from the Agency for Covert Rare Operatives, a secret organization that handles people with extraordinary abilities, everything from weather control and psychic talent to feral shifting and stranger powers that are hard to explain in one breath. The mood is hot, fast, and a little gleefully over the top.

The run of books, starting with Riding the Storm, introduces the basic setup. An agent or target with unusual abilities gets pulled into a dangerous mission, attraction flares immediately, and somebody powerful wants to weaponize those gifts. Unleashing the Storm and Seduced by the Storm keep building that world through different couples and different powers, while Taming the Fire, Tempting the Fire, and Taken by Fire widen the scope with shape shifters, jungle missions, experiments, and rival agendas. Later stories like Three the Hard Way show the world can also handle darker emotional fallout and different relationship shapes.

Think secret agents, superpowers, and a lot of bad decisions made for good reasons.

What ties the series together is the sense that gifted people are always in danger of becoming someone else's property. ACRO recruits and protects, but it also operates in a gray zone. Outside groups want to capture, breed, study, or exploit rare operatives, and the books get a lot of tension from that push and pull between freedom and control. The romance is central, but there is almost always a mission clock ticking in the background.

The settings help keep the series lively. One book might send you to the Louisiana bayou, the next to an isolated Idaho farm, then a Florida bar, a London club, or the Brazilian rainforest. The powers are varied enough that each book feels a little different, but the tone stays consistent. These are not quiet fantasies. They are action-heavy, high-heat stories that know exactly how pulpy they want to be.

If you are coming to Larissa Ione for the demon mythology, ACRO may surprise you. If you want superpowered romantic suspense with military energy, covert ops, and a shared-world cast that keeps crossing paths, it is a good rabbit hole. Start with Riding the Storm and keep going in order, because the agency politics and recurring faces are part of the fun.
