rape is mentioned as a backdrop of the context of the book and often brought up in small portions of detail, like in relationships betwixt gods/goddesses/mortals
The sea nymph Thetis is raped, and it is somewhat graphically described on page 19. Discussion of her subsequent PTSD continues onto page 20.
There is also discussion on pages 58-59 of female slaves who are forced into sex by the men of Peleus's house. Their pregnancy after is also mentioned. There is a line that says that these relationships are not always rape, but it is also possible that is just what the men tell themselves.
There are ghosts of sorts involved in Greek mythology but it's not really relevant. There's something from the POV of a ghost near the end but nothing intended to be creepy involving ghosts at all
Yes, but not related to gender. The protagonist is born with one name and given another after being exiled. He also gives himself a name. He is called by different names throughout but is not offended by any of them
They’re not outright bisexual but kind of fits the category; Achilles is in love with a man but marries and impregnates a woman, leaves her for the man. Patroclus sleeps with the same woman.
a medical tent on a battlefield is used as a makeshift hospital and there are scenes taking place within it, but there is no modern medical equipment or etc.
there are a few points that could be considered meltdowns but they dont linger on that for very long during any time. Most of it is aided by the character being consoled to some degree
It isn't meant as a threat or manipulation but there is heavy implications that if achilles or patroclus died before the other, they would kill themself to be with the other. At one point patroclus says that if achilles died he "wouldnt be far behind".
The first thing that is said about the protagonist’s mother is that she is simple, which clearly has a negative connotation. The protagonist later realizes that the reason he was exiled was for appearing unintelligent, rather than for murder, which he assumed
There are a scenes where a man is dressed as a woman and it is brought up, but I wouldn't call it "jokes", it's more used as a form of possible blackmail
There is a point in the book where Achilles is forced to pose as a woman and is referred to as a woman (with she/her pronouns) by characters who do not know it is Achilles.
both main characters are lgbt and die by the end of the book - not sure how spoilery this is, since Song of Achilles is an adaptation of the Iliad and Patroclus's and Achilles's deaths are quite notorious from the original material
several mentions of sex as well as young pregnancies. there are three scenes with explicitly sexual content. though the prose writing is designed to make them fairly "poetic", two of the three would be considered graphic. easy to spot them before they happen, each lasts around a page or two.
