I love Maria and Peter!  I loved this whole series, but I love that both MCs are plus sized and they have a shared experience over being plus sized in TV, versus previous books in the series where the FMC is plus sized and the MMC seems to be totally ripped and gorgeous.  The whole story felt very down to earth despite it being about tv stars.  Honestly I don't think there's a single character in this series that I don't like.  Except for Ian and the show runners of course.
