I enjoyed North's previous novel , with some reservations. This one was similar. I read it in a day — it's quite the page-turner — and it has a compelling plot trigger.
The first-person narrator is an entity who can jump into any human body from its current host, just by making skin-to-skin contact — the "touch" of the title. Male or female, young or old, it doesn't matter. The host doesn't know anything about it while they are possessed, and is left unharmed — unless, of course, something happens to their body while the possessor is in control.
Sounds pretty gruesome like that, so it's impressive that our sympathies are with the narrator throughout.
Good story, slightly flat ending. Hey-ho.
