The House of Hades

Loved leos story line in this but the others were quite boring. Percy and Annabeths got a big repetitive but still cool

Spoilers ahead?? I think?? not sure if they count as spoilers
⚠️
No character deaths? Well no important character deaths. No one has died in this series which makes me less attached. All good series have a death that rips you apart. At this point at least 5 characters have to die in the final book to make up for everyone surviving the whole series
