Puns, fun and Canadiana-they're all standing on guard for solvers in O Canada Crosswords 17. These ninety-five new crosswords provide a playful mix of sixty-five Canadian- and other-themed puzzles in larger grids, plus thirty non-themed Canada Cornucopia crosswords.

For anyone passionate about puzzles, author Gwen Sjogren's books are a go-to source for an invigorating crossword-solving experience. This collection taps Canadian themes like Retail Therapy, NHL Icons, Power to the People and Urban Islands, as well as whimsical offerings like Hair Today, Gone Tomorrow, Loco Loci and You Had Me at Hello.

To further put solvers' wits to the test, ten crosswords have no fill-in-the-blank clues. And for an added element of intrigue, Sjogren debuts "Puzzle Link-up" where figuring out the themes of four consecutive puzzles allows solvers to unlock the theme of a fifth.

So get your pencil (or pen) ready, engage your brain and see thee rise to the challenge of O Canada Crosswords Book 17!
