I know absolutely nothing about F1 racing, and I still found this book enjoyable. 
The pros: the likable friend group, relatively good communication, solid friendship base, brother’s reaction to finding out.
The cons: said “I love you” way too fast, pacing was weird, relationship went from 0 to 100 very fast, the sudden ending.
I liked it enough that I think I will plan to read the next book in the series.
