"Great, kooky, monstrous fun!" - Jim Benton, bestselling author of Franny K. Stein
"A visually interesting mix of illustration and story, punctuated by numerous lists, comic panels, and cartoon diagrams and led by a smart female protagonist. A bubble-gum crowd pleaser with wide audience appeal." - Kirkus Reviews
"This laugh-out-loud book is a perfect pick for transitioning readers with a penchant for silly stories, or graduates of the Fly Guy series." - Booklist
"Researching the creature she dubs Meh fills Olga's days with purpose and her notebook with hilarious quips ("He doesn't like it when I put a sock on his head. . . . He's really scared of bananas"), which Gravel captures in her signature brand of chunky cartooning, accented with red." - Publishers Weekly
"Readers will get lots of laughs out of the steady stream of gross-out jokes, as well as Olga's misanthropic humor, though her attitude toward humans softens slightly by book's end." - Publishers Weekly
"An apt readalike for fans of Wimpy Kid, and Gravel deploys spot art, larger illustrations, word balloons, and chunks of text with great success in the layout." - Bulletin of the Center for Children's Books
"[An] obvious sell to fans of animals, but it will also hit a humorous note with anybody who has felt a little left behind by these things we call humans." - Bulletin of the Center for Children's Books
"For fans of Dork Diaries and Captain Underpants, Olga will be a big hit. Kids will devour the toilet humor along with the quick one-liners Olga throws out." - School Library Journal
"Animal-loving Olga makes her biggest scientific discovery yet in this amusing story!" (Recommended on "The Ultimate Summer Reading List for 9- to 12-Year-Olds-2017 Edition") - Brightly
