Exactly. Though it would involve a lot of work, and I think that to appeal to steadfast fans, it will still have to involve a walk, and a penitential mode.
I'd probably suggest she walked, solo, a particularly difficult and remote bit of the Camino off-season or something, only she's too well-known now, she'd be recognised a lot.
I mean, in PRH's shoes, I wouldn't be cutting her off either.
@GogleddCymru -- yes. that would feel much more likely to me. A two-book deal initially, but with a clause meaning the second book doesn't happen if the first one tanks. And then another two-book deal when TSP is huge. TWS has the feel of a sequel to a massively successful book that doesn't really know what it's doing, quite. There's her mother's deathbed, moved from its original position in TSP, which gets a bigger focus, and Moth's health after TSP, because so many of the interviewers and fan questions at book events focused on that, and the appealing idea of retreating back to the land on the cider farm, and then a walk (which may not, as various people on here have pointed out) have taken place at all close to where it purports to happen in real time), and which is short and not exactly exciting. (The main jeopardy is Moth forbidding Ray to tell Dave and Julie he's not coping, and some arbitrary subplot about a woman in red trousers and the people she's walking with.)
Clearly an editor said after TWS, 'Look, Raynor, you need a better hook, and a better walk, for the next book', hence the Big Walk of Landlines.
