I was looking for something fluffy and easy to read that wasn't terrible, and I was intrigued by Resenting the Hero since it was on both a Kirkus review list, "Top 10 Fantasy Novels by Female Authors," and the Goodreads list for "Wonderful books with Awful Covers." (In my opinion, the title is awful as well...) Clearly, the cover for this book is awful, combining the worst of cheesy fantasy covers with the suggestion of romance, but at least the guy on the cover isn't shirtless with an oily chest. Also, if this awful cover was designed to snare people wanting to read fantasy romance fare, those readers would be disappointed since the two main characters don't end up together, and I personally hope that that don't in future volumes, though I wouldn't be surprised if they did. Although I wouldn't necessarily call the book "wonderful," I was pleasantly surprised.
The world and magic system are different enough to be refreshing, although I would've liked it better if both had been developed in more detail. I suppose that the setting might become more fleshed out in the following (six!) volumes, but I got the feeling that main reason that the world and magic weren't further developed was because they weren't particularly fleshed out in the author's mind. However, the idea of a partnered Source (who prevents natural disasters by channeling away the elemental energy) and Shield (who protects the Source's body and mind from being destroyed while channeling) provides opportunities to explore partnerships/roles in general, personality traits valued by society, learning to form one's own opinions, and even a little bit of politics.
Sources and Shields are ideally identified as young children and then taken to the Triple S Academy where they are isolated from the outside world and trained until adulthood. When their training is finished, Sources and Shields are ideally bonded and then sent out into the world to prevent the planet's otherwise devastating natural disasters. Whether by nature, academy training, or both, Sources tend to be, or are at least stereotyped as, extroverted, charismatic, take-charge people who have a tendency towards hedonism while Shields seem to be introverted, reserved and responsible. In Resenting the Hero, it becomes evident that both society and the academy are doing both Sources and Shields a disservice by pigeon-holing them in such a way, both by treating like Sources powerful but temperamental and petulant children that much be baby-sat by their Sources, and undervaluing Shields by allowing them to be treated, or at least perceived, as less-valued servants for their Sources.
In the novel, there are also suggestions that Triple S may not be as benevolent as it seems for various reasons: the requirement that potential Sources and Shields are taken at such a young age from their family and isolated so that the only teachings, home and friends that they know belong to Triple S; the teaching and reinforcement of Source-Shield roles; the punishment of both members of a Source-Shield pair even if only one partner made an error; the potential that Triple S cultivates Source-Shield bonds which may prove incompatible; and the idea that Triple S may be a fascist state-within-a-state (akin to Babylon 5's Psi Corps) that holds too much power (since without it, natural disasters would destroy any settlements on the planet and lead to uncountable loss of life) that leeches off the public (Triple S and any Source or Shield needs are completely free, funded by taxes).
I like the fact that Moore alluded to all of these things, but didn't necessarily make it black and white. While there were some characters who fit the stereotypes for Sources and Shields, including the main characters many times, they didn't always. Furthermore, although the "villain" of the story was insane and attempted to change Triple S for all the wrong reasons and was ultimately defeated, the propoganda he fed to the mob about Triple S and the changes that he would supposedly make weren't without the possibility of truth.
I suppose that if I pick up the next book or books I'll find out if these themes were further explored and if the partnership between the two main characters remains entertainingly sarcastic (similar to Korean drama flirting rather than typical American romantic comedies) and platonic.
