The White Queen sleeps and will not wake. Black shadows have fallen across her kingdom. The balance between Dark and Light is broken and only the MIRRORMASK can restore it. So Helena, a stranger in a strange land, embarks on an epic quest to find the missing charm before darkness envelops the Dreamworld forever. Written by award-winning fantasy writer Neil Gaiman, MIRRORMASK is a phantasmagorical treat for the eyes and mind, a wondrous blend of live action and CG animation, where strange, magical creatures dwell in a fantasy world of unbridled imagination and scope, as told through the spectacular, cutting-edge visuals of designer/director Dave McKean.

Trigonometry has always been the black sheep of mathematics. It has a reputation as a dry and difficult subject, a glorified form of geometry complicated by tedious computation. In this book, Eli Maor draws on his remarkable talents as a guide to the world of numbers to dispel that view. Rejecting the usual arid descriptions of sine, cosine, and their trigonometric relatives, he brings the subject to life in a compelling blend of history, biography, and mathematics. He presents both a survey of the main elements of trigonometry and a unique account of its vital contribution to science and social development. Woven together in a tapestry of entertaining stories, scientific curiosities, and educational insights, the book more than lives up to the title Trigonometric Delights.
