update 07 May 2017 : reread before the next book because I had forgotten absolutely everything about it! I still don't feel like that much happened to the main characters of this new series, but still so lovely to see the faces and places I love back in my lives.
Basically, this first book is an introduction at what is to come, and I can't wait to actually really get into it with the next book that is waiting for me right now.

THIS REVIEW IS IN FRENCH AND IN ENGLISH.

FR : Oh Rick ... J'avais oublié à quel point vos livres étaient drôles. Impossible d'arrêter de sourire tout au long de ce livre !
Je ne pensais pas qu'on reverrai autant des personnages qu'on connaissait déjà et ça m'a ravie de les revoir ! J'attends avec impatience de revoir les autres.
Bien que j'ai aimé les personnages d'Apollon et Meg, j'étais quand même beaucoup plus entraînée par les lieux qu'on revisite, les personnages qu'on revoit, le monde dans lequel on re-rentre. Mais je pense que je serai plus impliquée par l'histoire dans les prochains livres.

EN : Oh RIck ... I forgot how much your books were funny. It was impossible not to smile or laugh throughout the entire book !
I didn't expect seeing as many characters we already knew as we did, so I was so pleased by it ! I can't wait to see the others.
As much as I enjoyed reading about Apollo and Meg, I felt so much more when I was reading about places and people I already knew and loved. I do believe I will get even more into the new characters as the series goes along however.
