Book excerpt: A debut novel of love, narcissism, and ailing cattle Idiopathy (?d?'?p??i): a disease or condition which arises spontaneously or for which the cause is unknown. Idiopathy: a novel as unexpected as its title, in which Katherine, Daniel, and Nathan—three characters you won't forget in a hurry—unsuccessfully try to figure out how they feel about one another and how they might best live their lives in a world gone mad. Featuring a mysterious cattle epidemic, a humiliating stint in rehab, an unwanted pregnancy, a mom–turned–media personality ("Mother Courage"), and a workplace with a bio-dome housing a perfectly engineered cornfield, it is at once a scathing satire and a moving meditation on love and loneliness. With unusual verbal finesse and great humor, Sam Byers neatly skewers the tangled relationships and unhinged narcissism of a self-obsessed generation in a remarkable, uproarious first novel.
