i am unsure of how to rate this book, so im going with a neutral 3 stars.
My introduction to Alice Oseman was Heartstopper. And knowing that this was connected to it, i wanted to read this book. I was not prepared for the change of tone. At all.

Solitaire is the 1st book by Oseman, at 17 years-old (btw there's definitely points that show the young-author vibe), but/and it is much darker than its fellow comic. The story was a bit unbelievable at times, but i did manage to read it all in one sitting, reminiscing about highschool feelings.
