Review(s):
“The short length, breathless pace, and graphic-novel-esque, full-page illustrations might make this one appealing to reluctant readers.”–School Library Journal “There’s peril aplenty, but Smith keeps the tone light and easy, making this accessible to younger readers averse to anything truly scary.”–Bulletin “This is exactly the book young dino fans would write themselves, crammed with sandbox-style action and positively packed with words like Nanotyrannus and Parasaurolophus.”–Booklist
