Emma and the Silk Thieves - Tales of Widowswood, #2

Once again safe at home, Emma clings to the comfort of family and tries to put the fright of the Banderwigh behind her-but deeds, even good ones, often have consequences. With a new reality of spirits and magic open to her, Emma feels a strong connection to Widowswood. She means to make good on her promise to the Spider Queen, bringing a monthly supply of silk in trade so humans cease their trespass upon the forest.
A guild of thieves infiltrates the quiet town, lured by the incredible value of enchanted spidersilk flowing so freely from the forest. At first, they don't realize the source is a ten-year-old girl, but once they learn, they'll do anything to control her. Stuck between protecting her family and protecting her forest, Emma draws courage from her grandmother's stories and makes a choice-that could cost her life.
