Well, that was a fun read. Maybe I would've liked the story more if I'd read this when I was younger. 
Just like the next book, 'Trouble Makes A Comeback' (I actually read the second book first before book one it was an instant purchase at the bookstore back in 2021, I didn't even bother reading the synopsis where it clearly said it's part of a series), there's a lot of mischief, trouble, quirks, witty dialogues, and some high school stereotypes involved in this one. 
The mystery wasn't that 'intense' though which is a bit reasonable since it'll be resolved in the next books. If you're looking for a fast-paced and easy read, pick this one up.
