while nice to visit characters from books' past, it had little to no depth. beyond fluffy, rushed, syrupy sweet. I need to 'know' the characters, and even while in their heads, they were complete stangers to me. needed more development - something. 
 I liked seeing our past MCs, but as they we no longer the focus, the reader missed out on learning this book's characters. 
 another oddness, the two novellas didn't flow together. 
 1: 19 yo college student adult. 
 2: 14 yo freshman child. Too much of an intellectual, age, and generational gap to be back-to-back. 
 Duff & Midsummer's nightmare were on the older end of YA (16 yo+). this led secrets & lies to be aged down for younger readers (12 yo, maybe younger) so I felt weird reading something so young in comparison to the book's previous installments. still love the author, tho.
