When the aliens came, they didn't attack - they just hung in the sky. After a year of human hysteria, they left and the rains began. Ever since, some girls have been born with unusual abilities. The fifth daughter of Magnus Roma, creator of the extraordinary circus called The Show, Penn was born a Celestine: she can call down the stars. Her newborn cries brought burning hail that killed her twin brother. For 16 years Penn has hidden her power by assuming the life of her twin, just as her four older sisters (who can manipulate the elements) have hidden from the Wardens' Commission in plain sight as circus performers.
Then, one explosive night, Penn loses everything. The wardens want to protect Earth from anything alien. Her sisters are taken, and The Show is destroyed. To save her family, Penn must do the unthinkable and use the power she's been taught to suppress. She'll travel to the very heart of her world's darkness and discover the truth about her terrifying gift.
