The Lost Daughter of Sparta by Day, Felicia

THE INSTANT NATIONAL BESTSELLER * Felicia Day, actress and New York Times bestselling author returns with a "stirring, beautifully illustrated hero's journey overflowing with heart and a wicked sense of humor" (Ernest Cline, #1 New York Times bestselling author) about the lost mythical character of Philonoe--Helen of Troy's sister.

Helen of Troy. Clytemnestra. Timandra.

Three sisters, infamously cursed by the goddess Aphrodite to betray their husbands, are known the world over. But few know about the fourth sister: Philonoe. Lost to historical record, ancient texts say she had a different fate than her sisters. But why and how did this happen?

New York Times bestselling author Felicia Day and illustrator Rowan MacColl bring Philonoe to vivid life at last, in The Lost Daughter of Sparta.

A magnificent hero's journey with a feminist twist, The Lost Daughter of Sparta fills in history's missing pieces with sparkling wit and pathos, thrilling adventure, and an empowering love story that won't soon be forgotten.
