Although there is a prohibition to read books about idolatry or even say their names (Rambam Avodah Zara 2:3), R. Moshe Feinstein (Y.D. II 53) has stated that, like in other halakhos of Avodah Zara, we need not be concerned if that form of idol worship has been annulled (which in this context means that nobody worships it anymore).

While there's no prohibition in reading about fictional 'gods' per se, reading novels is not a simple matter. The Yerushalmi (Sanhedrin 10:1) states that reading'books of Homer' is like reading letters and permissible, but most poskim imply otherwise. The Shulchan Aruch (O.C. 307:16) seems to prohibit reading all novels as does Tosfos and Rosh to Shabbos 116b, and the Rambam (Commentary to Mishnah Sanhedrin 10:1) is particularly emphatic that one who reads books of stories, "kings and their behaviors", wastes time and doesn't deserve a share in the World to Come. These days, it seems that many Rabbis take it for granted that we need some form of entertainment, and it's probably better than doing nothing, as בטלה מביאה לידי זימה (idleness brings about lewdness - Kesubos 59b), but this is a sensitive matter and should probably be brought to your LOR (local Orthodox Rabbi). More importantly, contemporary novels (even ones written for teenagers) may contain what many b'nei Torah consider to be 'inappropriate material'. (I wouldn't know about this series as I've never read them, sorry).

I'm not entirely sure if I understood from Wikipedia what's considered a 'novel of kefirah', but when it comes to books that one might suspect would lead one away from God there's the explicit prohibition of 'אל תפנו אל מדעתכם' - do not remove God from your minds (Shabbos 149, see Igros Moshe quoted above). While there may be dispensations in order to know how to respond to a heretic (Rambam, Rashbatz and R. Yakov Emden to Avos 2:2, Meiri to Sanhedrin 11:1), I would still ask your LOR here to: the answer may be different depending on the individual book as well as the personality (and possibly level of religious commitment) of the person asking the question.

However, R. Yair Hoffman believes that even Rav Moshe would prohibit reading about idols and idolatrous practices unless it is portrayed in a negative light.
