Syfy says it has renewed its U.S. drama series \"Lost Girl\" for a 13-episode third season to begin airing in January. \"Anna Silk stars as seductress Bo, a Succubus -- a powerful female entity in folklore -- who feeds off sexual energy,\" said a synopsis of the show. \"Raised by human parents, Bo had no reason to believe she was anything other than the girl next door -- until she \'drained\' her first boyfriend to death. Bo discovers she is one of the Fae, creatures of legend who pass as humans while secretly feeding off them. Faced with choosing between an allegiance to the Dark or Light Fae clans, Bo takes the middle path between the human and Fae worlds while embarking on a mission to unlock the secrets of her origin.\" Also returning for Season 3 are cast members Kris Holden-Ried, Ksenia Solo, Zoie Palmer, Rick Howland and K.C. Collins. Joining the ensemble will be Rachel Skarsten.
