Book excerpt: A young woman is haunted by the ghost of her conjoined twin, in Lisa Brown's The Phantom Twin, a sweetly spooky graphic novel set in a turn-of-the-century sideshow. Isabel and Jane are the Extraordinary Peabody Sisters, conjoined twins in a traveling carnival freak show—until an ambitious surgeon tries to separate them and fails, causing Jane's death. Isabel has lost an arm and a leg but gained a ghostly companion: Her dead twin is now her phantom limb. Haunted, altered, and alone for the first time, can Isabel build a new life that's truly her own?
