They are the last survivors of their race beings who live on and communicate through energy, who are capable of assuming the shape of any other species. When their youngest member is assigned to a world considered safe to explore, she is captured by the natives. To escape, she must violate the most important rule of her kind, and reveal the existence of her species to a fellow prisoner—a human being. Now her race is in danger of extinction, for even if the human does not betray her, the Enemy who has long searched for her people may finally discover their location. Esen-alit-Quar, Esen for short, Es in a hurry or between friends. The dear little blob has only begun her adventures.

The first book in Julie Czerneda's acclaimed Web Shifters series made the Nebula preliminary nomination list in 1998. Changing Vision continues the story of Esen, the last survivor of an alien race with the ability to assume the form of any creature. Now Esen must break her species' rule of noninterference—to keep interspecies tension from escalating into all-out war....

Picco’s Moon was where it all began for Esen-alit-Quar, Youngest of Ersh’s Web. It was here where Ersh, the Oldest, had chosen to make her home; here, too, where Esen received her early training as a shapeshifter and a member of the Web. When Ersh’s Web was destroyed, Esen and her human friend Paul survived, and together they founded Esen’s Web, a group composed initially of the two of them but one which expanded slowly to include a chosen few selected by Paul. For in their universe there were all too many species ready to destroy Esen, should they discover her true nature. Still, despite the need for concealment, life had been good to Esen and Paul. They now had well-established identities, a thriving business, and numerous friends. It seemed as though they’d finally created a safe haven for themselves. At least until they received word that someone was mining Picco’s Moon, desecrating Ersh’s Mountain. Esen and Paul had no choice. They had to go to Picco’s Moon and put a stop to the situation. But before they could even set out, they found themselves under attack on every front. Their carefully built haven gone, and loyal friends suddenly transformed into vengeful enemies, was there anywhere Esen and Paul could run, anyone they could turn to for help, any way to defeat a foe they couldn’t even identify?

This exclusive e-novella, set shortly after the events in Hidden in Sight, features the first glimpse of the All Species' Library of Linguistics and Culture in the Web Shifters sci-fi series. The Human Commonwealth has spread into a section of space well and truly claimed by others, a wealth of intelligent species who doubt we've much to offer. The only recourse? Diplomacy! At least that's what Evan Gooseberry, assigned to the Human embassy on Urgia Prime, firmly believes. Enough to fight his own deep terrors and remain where even a walk outside is an exhausting challenge. But what happens when a species' misunderstood biology is its diplomacy? The stakes are high; the situation desperate. Doubted by his superiors, Evan stands alone. Unless he can accept help from the strangest alien of all: Esen-alit-Quar, Esen in a hurry, Es between friends. Having come to Urgia Prime with her friend Paul on their own mission, the remarkable Webshifter is willing to do whatever she can. There's only one problem. Esen is everything Evan Gooseberry fears.
