I read a lot of YA novels, and the beginning stages of this one made me believe it was too specifically aimed at a more teenage demographic. The early chapters seemed juvenile in part, and lacked depth. I nearly abandoned it. 
 I'm so glad I didn't. 
 The lacklustre start gave way to a host of well-developed main characters, and intriguing secondary characters, set in a wonderful (?)medieval world of magic. The plot has Senna at the centre, the last witch, standing against Espen and her followers to reclaim the witches' natural power and affinity with nature, and free the rest of her kind. Senna develops from a naive and innocent young girl to a witch with a powerful song, and it is believable and relatable because of the struggles she endures to get there. Through loss and abandonment, she pushes past her fears and insecurities, despite them never fully leaving her. Her insecurity is a flaw which follows her throughout the book, but it is justified, due to her sheltered past, and the ill-treatment she receives as a witchborn. 
 Witch Song is a beautifully written book, with its magic based in the pagan tradition and style of nature. I'd recommend it for anyone who, like me, finds themselves drawn to books with old witch magic.
