I liked this first instalment in the PLL series - quite silly and an easy read.
I think for me, it's a bit of YA guilty pleasures, but I did think that the characterisations were done quite well and we got a feel for each of the four girls.
But... I simply don't care enough about what they're wearing and it gets quite tiresome after awhile to have to read a whole paragraph of brand names whenever anyone meets! EVERY time!
