More good help from Louise Harnby, via Chris the Story Reading Ape. This piece on point of view contains some excellent, clear examples if POV gives you fits.
No names shall be mentioned, but I’ve been seeing an awful lot of “head-hopping” in works by some well-regarded authors; I’ve learned not to gripe when it’s clear writers have built up faithful followings for whom what bugs me doesn’t even register.
Still. It DOES bug me. The minute your reader stops to scratch their head, you’ve lost them, even if for only a moment.
So I say, be purists about point of view!
