How the perception of shadows, studied by vision scientists and visual artists, reveals the inner workings of the visual system. In The Visual World of Shadows, Roberto Casati and Patrick Cavanagh examine how the perception of shadows, as studied by vision scientists and visual artists, reveals the inner workings of the visual system. Shadows are at once a massive problem for vision—which must distinguish them from objects or material features of objects—and a resource, signaling the presence, location, shape, and size of objects. Casati and Cavanagh draw up an inventory of information retrievable from shadows, showing their amazing variety. They present an overview of the visual system, distinguishing between measurement and inference. They discuss the shadow mission, the work done by the visual brain to parse, and perhaps discard, the information from shadows; shadow ownership, the association of a shadow with the object that casts it; shadow labeling, the visual system's ability to tell shadows from nonshadows; and the shadow concept, our knowledge about shadows as a category. Casati and Cavanagh then apply the theoretical apparatus they have developed for shadows to other phenomena: illumination, reflection, and transparency. Finally, they examine the art of the shadow, paying tribute to artists' exploration of shadow, analyzing a series of artworks (reproduced in color) from a rich and fascinating art historical corpus.

Schwab "Addictive and immersive, A Gathering of Shadows cements this series as a must-read." —Entertainment Weekly, grade A Four months have passed since the shadow stone fell into Kell's possession. Four months since his path crossed with Delilah Bard. Four months since Rhy was wounded and the Dane twins fell, and the stone was cast with Holland's dying body through the rift, and into Black London. In many ways, things have almost returned to normal, though Rhy is more sober, and Kell is now plagued by his guilt. Restless, and having given up smuggling, Kell is visited by dreams of ominous magical events, waking only to think of Lila, who disappeared from the docks like she always meant to do. As Red London finalizes preparations for the Element Games-an extravagant international competition of magic, meant to entertain and keep healthy the ties between neighboring countries-a certain pirate ship draws closer, carrying old friends back into port. But while Red London is caught up in the pageantry and thrills of the Games, another London is coming back to life, and those who were thought to be forever gone have returned. After all, a shadow that was gone in the night reappears in the morning, and so it seems Black London has risen again-and so to keep magic's balance, another London must fall...in V.E.

"Wonderful . . . J. V. Jones is a striking writer." So says Robert Jordan, the author of The Wheel of Time epic fantasy series. And Jones lives up to that praise in the highly charged epic adventure of Ash March and Raif Sevrance, two outcasts whose fate are entwined by ancient prophecies and need, in the cold, dark world that threatens to be torn asunder by a war to end all wars. Isolated by their birthrights, they are but two who fight the dreaded Endlords, and their strength and courage will be needed if the world is to be saved from darkness." Raif, wrongly accused and cut off from his clan by the treachery of their new headsman, has a talent for killing that is part of his curse and his burden. But he bears another burden of greater weight. Ash is a sacred warrior to the Sull, an ancient race whose numbers have declined. Raised as a foundling, never knowing her true history, she must learn to accept the terrible gifts of her heritage. But as Ash learns more of her greater fate, Raif's task looms dark and desperate, for he must journey through the nightmare realm of the Want, a place where even the Sull now fear to tread. For deep within the Want is the Fortress of Grey Ice, and there he must heal the breach in the Blindwall that already threatens the world. Should he fail, not even Ash's powers can save them. . . .
