I was going to be an ichthyologist when I grew up. I was going to live in Australia or Indonesia or Belize or the Red Sea and spend most of my day submerged in that same warm water. A fishtank stretching thousands of miles. The problem with the aquarium was that we couldn't join them.

Twelve-year-old Caitlin lives alone with her mother in subsidised housing next to an airport in Seattle. Each day, while she waits to be picked up after school, Caitlin visits the local aquarium to study the fish. Gazing at the creatures within the watery depths, Caitlin accesses a shimmering universe beyond her own. When she befriends an old man at the tanks one day, who seems as enamoured of the fish as she, Caitlin cracks open a dark family secret and propels her once-blissful relationship with her mother towards a precipice of terrifying consequence.

In crystalline and graceful prose, Aquarium takes us into the heart of a brave young girl whose longing for love and capacity for forgiveness transform the damaged people around her. Relentless and heartbreaking, primal and redemptive, Aquarium is a transporting story from one of the best writers working today.
