Solitary Witch: The Ultimate Book of Shadows for the New Generation by Silver Ravenwolf

This book has everything a teen Witch could want and need between two covers: a magical cookbook, encyclopaedia, dictionary, and grimoire. It relates specifically to today's young adults and their concerns, yet is grounded in the magical work of centuries past. It is organised so that readers can skip over the parts they already know, or read each section in alphabetical order.
