2014 Eisner Nominee
A Junior Library Guild Gold Standard Selection

"Readers get a crash course in palindromes (and what’s really important where birthdays are concerned) as Otto travels through the professor’s gateway...The oddities of the backwards world provide fast-paced thrills...There’s a message about the importance of friends and family underlying the story, but Cammuso’s action-packed cartooning keeps the emphasis on fun."
--Publishers Weekly

"Don’t get me wrong; I love kids. But paragons of putting other people first they are not, and so – like the rest of us – they sometimes need reminding that they’re not the only important person in the room. That’s why books like Otto’s Backwards Day are so welcome, especially when they’re as entertaining, adorable, and non-didactic as this one is."
--School Library Journal, Good Comics for Kids

"Otto the cat is back and as comically headstrong as ever."
--Seacoast Online
"There’s a lot to keep readers engaged, and grown-ups will giggle as much as their kids."
--School Library Journal

"Strewn with palindromes and reversed words that even emergent readers will have no trouble decoding, the miniodyssey leaves Otto in the right place: back home, partying with newly appreciated friends and family until latest invitee Evil Olive arrives with the stolen goodies... A snappy follow-up to Otto’s Orange Day, gift-wrapped around a worthy theme and frosted with tasty wordplay."
