Thalia Kostis will be the first to tell you it's not magic, it's theoretical math when she walks a Möbius strip through walls to her office at the Institute for Applied Topology. CIA Case Officer Bradislav Lensky doesn't care what it is, as long as she can help track down a smuggling ring and the terrorists in their safe house in Austin. The other magicians nearby don't agree, and don't care for new rivals either! Now Thalia and the rest of her misfit crew are in a race against time, terrorists, common sense, grackles, and their graduate advisor to save the day!

Any sufficiently advanced applied math is indistinguishable from magic... Protest on campus are usually like grackles - annoying, in the way, and ignorable. But when Thalia Kostis invisibly crashes a meeting, she learns that outside money and organizers are planning for a full-out riot, complete with scapegoats and martyrs. Unfortunately, applied math isn't magic, and she’s in danger when her cover’s blown . Now she and the rest of the misfits at Institute for Applied Topology must figure out who's behind this and stop it, before more than just their own building goes up in flames!

Problems come not as as single corvids, but as full flocks... Life at the Center for Applied Topology is never precisely normal, but Thalia Kostis, Brad Lensky and their coworkers have been enjoying a brief run of peace, quiet, and optimizing the theorems that allow for teleportation and camouflage. Everything is within parameters, until they get saddled with an intern who's convinced that he's God's gift to math and that their applications of topology are illusory. A rebellion is brewing - but bigger problems are afoot. Their old enemy, the Master of Ravens is back, and has teamed up with a mercenary with a grudge over the Center’s recent disruption of a profitable contract. Together, the two are planning on taking out the Center - and everyone in it!

Thalia Kostis is a budding magician (depending on how you define it), but she has a theoretical mathematician's grasp on socialization and people skills. When pressed into spying on a rival magician's company retreat to find out where kidnapped coders are being held, she expected things to go completely sideways. She didn't expect to end up mistaken for her rival's fiancée... Now she has to juggle her own impending wedding, her cover, her magic, and company politics that might turn out deadlier than anyone expected!

Thalia Kostis and her cohort knew the CIA was funding their group of research mathemagicians, but they'd never demanded results like this before! After terrorists use magic to kidnap hostages from the agency's headquarters, the Center for Applied Topology finds themselves torn from their cubicles and dragged across three continents, from holding cells to terrorist safehouses as the superiors who never believed in them before are now demanding impossible results. Now academics who can't organize a donut run are finding out there are worse fates than loss of funding... If they don't find and stop the magicians responsible, they're going to lose their lives!

The CIA has embraced mathemagics, but only as a new way of doing the same old thing: Planting bugs. Thalia and the rest of the Center for Applied Topology's research fellows have been dispatched across Europe with the mission of attending embassy parties, and teleporting back in later to plant bugs. Unfortunately, academics are the worst possible variable in the equations of diplomats and spies. The resulting hijinks, escapades, and misunderstandings end up with Thalia on one side of a Central Asian revolution, and her husband, case officer Brad Lensky, on the other... And if they can't figure out a solution, the entire country may go under water!

An old enemy, a new threat... When their son Aleksi is kidnapped, Thalia and Lensky are left wondering if the reason is ransom (bad) or revenge (worse). It'll take all Thalia's genius for applied topology (aka magic) to retrieve their baby - and meanwhile, the other topologists are turning into cats, getting jailed in the eighteenth century, and otherwise keeping life interesting.
