EHT – Kirkus Reviews

“In the great era of dinosaur-hunting, two teenagers accompany their paleontologist fathers in a race to discover the biggest of them all: the rex. A spirit of adventure permeates this fast-paced novel by the award-winning Oppel…. Rich in period details and dialogue, the story shifts between Rachel's and Sam's alternating first-person voices. Rachel's narrative reveals that she's one of the few white characters with enough conscience to reflect on the savagery of the explorers' treatment of the local Pawnee and Lakota Sioux. Suspense, romance, and the excitement of discovery make this Western thoroughly enjoyable.”
