A triumphant family story and sharply observed exploration of privilege, identity, and love in all its forms, following four estranged siblings whose lives collide in the lead-up to a family wedding, when new clues surface about their long-missing father.

April, May, June, and July Barber don’t have much in common anymore. An upcoming family wedding will place the four siblings in the same room for the first time in years. But shortly before, when April spots their father, who went missing while serving overseas a decade ago, their reunion becomes entirely more complicated.

While the siblings’ search for the truth about their father forces them back into each other’s lives, it also intensifies their private dramas. April loves her husband, but seeks excitement outside their marriage. May had big dreams for the future, but she’s still stuck living at home. June is eager to marry her girlfriend, so why does she need a drink at every wedding-related event? And then there’s baby brother July, whose unrequited love for his straight roommate has him more confused than ever.

An intensely personal narrative of loss, hope, and longing for a child. In this brave and lucid account, Julia Leigh broaches a challenging life event often left undiscussed: how the struggle to have a child can take an agonizing toll.

Leigh’s experience at the vanguard of medical science is acutely rendered, both physically and emotionally, transmitting what it feels like to so desperately wish for a child while knowing that the odds are stacked against you. From the daily shots she puts herself through at home, to hopes raised and dashed, and finally to the decision to stop treatment, Avalanche bears witness to Leigh’s raw desire, suffering, strength, and, in the end, transformation—a shift to a different kind of love.

The reader looks behind the scenes of a clinic and discovers how things really work: reality is a far cry from the slick marketing of the billion-dollar infertility industry. As for so many women, Leigh’s treatment failed, but her ghost child lingers in memory.
