The Pool of Two Moons is a 557 page fantasy novel written by the Australian author Kate Forsyth and first published in 1998. It is the second book in a series by Forsyth entitled The Witches of Eileanan, and it follows the novel by that title in the Bookshare collection. Subsequent works in this series are in order as follows: The Cursed Towers, The Forbidden Land, The Skull of the World, and The Fathomless Caves (published in 2002). A shortened version of the bookjacket's summary by Roc reads as follows:
Taking up where The Witches of Eileanan left off, we find Meghan o' the Beasts and her young charge Isabeau, outcasts in a land where magic has been outlawed. But the pair are soon separated, and Isabeau is wounded by witchfinders, and saved by a group of samaritans. Meghan sets out to find Isabeau's warrior-trained twin, Iseult, and a missing prince living under an ancient curse. Separately, the two parties must make their way through a land where magic is punished by death, seeking allies to spread the news--that the Witches are returning, and the Queen and her evil must fall.
