i loved it the first series of trials of apollo ive waited a long time nearly every day waiting for it to come out and when it did i bought it straight away io strongly recommend this to ANY Rick Riordan fans or people who LOVE mysterious, thrilling and adventure books because THIS is the BOOK for YOU.And No you dont have to get Ricks other books though the other books are also ABSOLUTELY AMAZING!!!!!!!!!!! so make sure to get this book you will not regret it because its worth it. **Spoiler** DO NOT KEEP READING IF YOU DONT WANT TO BE SPOILED OR JUST SKIP THE SPOILER BIT AND SCROLL DOWN.
I especially liked the bit Leo Valdez comes out because Leo is AMAZING!!!!!!!!! anyway i liked that and when Meg gets captured by myremeakes or whatever you call them and apollo saves her but then finds out that Megs Stepfather is Emperror Nero who wants to destroy Camp Half-Blood. i really liked that bit because it gives the BIG twist which is interesting.Thats really all i wanted to say.
