I've been all around the streets of Spokane hanging up posters for the May 1 Book Release Party.
Now it's your turn to find them.
How to play: Find three posters that look like this in three different locations. Take a picture of each exactly where you find it. Share them on this Facebook event page.
How to win: The first person to share three poster pictures on the event page, wins a signed copy of The Whole World at Once. Winner must attend book release party at Garageland on May 1, 2017 to collect this fantastic prize.
If you take a selfie with one of the three posters, then you'll get an even more fantastic prize.
