Riordan has crafted humour, meaningful diversity, and a talent for storytelling with this book/series and I am so here for it! I was actually floored at times because the diverse representation isn't just tokenism but is sincere and realistic. Everyone should give this series a chance. 
 As for this book in particular without spoiling anything, was a solid sequel. It kept pace with the speed of the first one considerably well, and doesn't leave room for dryspells, which I've come to find common in second books. This sequel has it's own plot arch and is not like many sequels that are used just to build up the third book.
