Leah on the Offbeat is a great book within the universe of Simon Spier. Whilst I personally prefer the original book, Simon Vs the Homo Sapiens Agenda, this is a good spin off whic features the same characters but from the viewpoint of Leah.
I will admit, that in the original book it was so gripping I couldn’t put it down, but in this novel the storyline is more complicated, slightly less gripping whilst still being a high quality product that can be read over several days.
Overall Leah on the Offbeat is a great book to compliment Simon Vs. The Homo Sapiens Agenda.
