Sleepwalk by Dan Chaon is a road-trip novel, Jim, but not as you know it. Our guy, Will, is a vigilante who does various jobs for an organisation he's not too concerned about. He doesn't ask questions - he does the jobs they want done, and he gets on with his life on the road in his camper van. He lives off grid with his dog, Flip. Until one day, someone tracks him down. She's convinced he's her father - he's convinced she's a scammer. Until he begins to come round to the idea of being a father - but can he trust this mystery woman? I loved this, I thought it was a really good adventure novel. I loved the road trip aspect, I really liked the protagonist, and even though it did descend into madness at times, I thought the author did a great job of getting it back on track. It reminded me a little of some of Stephen King's drama novels (with less sexism and fatphobia - love you, Steve, but seriously, dude) - the musical references were also perfectly placed. Every time a song was mentioned in the book, I played it while I was reading and it added an extra layer of fun to the experience. If you're looking for an adventure novel that reads like a fast-paced action film, doesn't drag on, and that touches on climate change, eugenics, artificial intelligence, shady billionaires, and fancy a few hours with a highly entertaining lead character (and his dog) then I recommend this one. I pictured him as Pedro Pascal, because the man lives in my brain now, but even just as a straight-up action novel it was a lot of fun. Thank you to @littlebrownbookgroup_uk for the ARC via Netgalley. I'm looking forward to discovering Dan Chaon's back catalogue!
