Astrid just wants to speak to her mother one more time, to thank her, even if it means losing her voice forever. Ling's family needs her to wish for food, even if it means she can't eat ever again. Callum wants to find his lost brother, even if it means losing himself forever. Icradus needs his father to come out of his trance, just once, or he'll lose his sister forever. All four of them are among the annual five chosen by the Selector to tell their wishes to the wishing well. Citizens of Hydaraforth Valley are chosen once a year to make their wishes come true, and the rules of the well are simple: -Only the five chosen by the Selector may make a wish each year. -The wish must be made for another, for better or for worse. -Your wish will retaliate upon you. -You must make a wish if you are Selected. -You can only be Selected one. But there is one other from Hydaraforth who's wish isn't as pure. The masked man who calls himself Tremor wishes for another to die, and himself gains immortality. But one wish isn't enough for him. Tremor seeks to master the well, and it's magic, and henceforth, the world. The only way to defeat him is to exploit the magic of the well, and reverse all of the wishes created by the well. But Asrid holds the threat of death if the wishes are reversed, for her mother wished for her to heal when she had the Cruciath disease, a deadly sickness that none of the villagers could heal. Ling will lose her father forever, for her grandfather wished to resurrect him. Callum will never see his brother again, the only family he ever had. And Icradus will lose his sister to her madness, and his father will never come out of his trance. All of these wishes, all of the losses, all of the gains, for better or for worse.
