Well, I don't think so, but there is one book that isn't in the series. It's called the Demigod Files . It's not technically in the series, but as I understand it, our loveable PJO characters are in there.
grover actually likes annabeth but he found out annabeth liked Percy so he had a heart broken but he still doesnt forget on annabeth and grover is not mad at Percy of annabeth liking him and Percy even knows grover likes her too usept annabeth and Percy loves each other and annabeth in the last book she kisses Percy on the lips ITS SO ROMANTIC THAT THEY LIKE EACHOTHER
Percy annabeth grover
Percy got attacked by echidna, then he fell into the river, meeting the water spirit or maiden or whatever.
If you've read the Percy Jackson & the Olympians, his enemies are Percy, Annabeth, and Grover.
Well there's codes for Annabeth , Percy and Grover's . For Percy's code it says "Percy's father is Poseidon the God of the Sea's . For Annabeth it says " Annabeths mother is Athena the god of wisdom ."And for Grover it says " Grover is actually a centaur" =p
