I went into this mentally preparing myself for a book that wouldn't be as good as Circe was, because honestly I really really loved Circe. I was pleasantly surprised with Song of Achilles, because it hit all the right notes and came out just as entertaining as Circe was. There's a bit more romance elements in this story than I remember there being in Circe (admittedly it has been a while since I've read Circe), but the character development of Patroclus and Achilles is exceptional. The ending especially was very well written, up to the very end.
