The Mark of Athena. by Rick Riordan

I liked the book because i couldn’t stop reading it.it drew me in. another reason i liked it was because i could refer to all the other books he’s wrote. I’ve read all the Percy Jackson ,  and the Olimpians books, and all the other Heroes of Olympus books. so i could easily make a reference. After reading those series, you practically must read this book. MUST READ. the only dissapointing part is it leaves you hanging at the end
