Betraying Season by Marissa Doyle (Published by Henry Holt, September 29, 2009)
After her twin sister, Persephone, marries - during her first London season, no less - teenage witch Penelope Leland travels to Ireland in the spring of 1838 with her former governess Ally, who is also newly married. Pen has never been as talented with magic as Persy, and would like to prove that she can be as good a witch as her twin. She hopes her studies in Ireland will enable her to do just that.
Shortly after her arrival in Dublin, Pen meets the handsome young Niall Keating. He begins to court her, and attracted to him, she enjoys it - even to the point where she is distracted from her studies. Unknown to Pen, however, is that Niall is acting on orders from his mother, who is also a powerful witch. Lady Keating wants to use Pen as part of a sinister plot against Queen Victoria. What wasn’t part of the plan was Niall and Pen falling in love with each other for real.
Betraying Season is a wonderful sequel to Marissa Doyle’s first book, Bewitching Season, but also manages to stand on its own for readers who haven’t read the first book. It contains a perfect blend of magic, romance, and history. I highly recommend both books to readers who enjoy young adult fantasy or historical fiction.
