Four years ago, Nessa’s careful life imploded when her husband disappeared during the first portal storm. Shimmering gateways to thousands of worlds appeared and vanished, sweeping away the unlucky. Later, the portals settled, but only a suicidal risk-taker would willingly touch one. Nessa rebuilt her life and her veterinary practice, now specializing in xenotics — the creatures that resulted from evolutionary paths on other worlds. But she still leaves supplies along the route Mark was traveling, in case he makes his way back. Hiking with a stranger to restock aid stations, Nessa realizes the portals have changed again. And this time she is the one in danger. Dive into the beginning of a dazzling science fantasy adventure with All Gremlins Great & Small, the novella that starts The Portal Storms.
