I saw an ad for it on FB the other day and stupidly didn't make a note of the name. This is the info I remember/ have to go on, Google isn't turning up anything so I'm hoping someone might have seen it or read it and know what I'm talking about!
Very bright pink and yellow cover
Author is young, 19 I think. Female and it's her first book. Possibly its won a prize
It miiiiight have the word mortal or mortally in the title. Or possibly the word critical
Author might be called Layla or something similar
I can't even remember what it's about but just remember thinking it sounded good!
