This tale could be summed up, almost, by a movie line from The Scarlet Pimpernell--"Look how they buzz round her, like bees to honey".
The world of Lilac Valley revolves, entirely on its axis, around the heroine, who is a socially conscious, top scholar, a published author/illustrator, a locally renowned chef, a sports car enthusiast, a nature expert, --oh, and a junior in high school! Of course, she is wholly unspoiled by the world and completely undiscovered by it until one day a boy happens to notice her practical shoes, starting a turn of events that explodes into a many-faceted jewel of opportunities. Suddenly, she has the vision and independence to fight for justice on many different levels, and at least three men, of different ages, are swooning at her feet, which, with her wide-eyed naivete, she is oblivious to. That could be acceptable to many Stratton-Porter readers (myself included) who have learned to appreciate the bright dreams of Utopian characterization (though I will admit, in my hypocritical heart, that while I love the "perfection" of her male characters I am often annoyed by the interpretation of it in her heroine's.)
It would be dramatically acceptable if not for the eye-opening racism that had an appalling, underlying theme. Here is the answer for those of us too young to have lived through the events leading up to the internment of the Japanese, who have ever wondered, "What were they thinking?!" This is no, "To Kill a Mockingbird" where the prejudices are portrayed as the enemy, this is a full-bodied embrace of what is referred to often, as "the Yellow Menace" and which ultimately emerges as a white supremacist conceit. It was hard to read but studied in the time period that it was written, through the hindsight lens of history, it could be an important reminder to us of how far we can stray when we are fearful and ignorant. So, in that light, it was a usefully alarming lesson to me.
Of course, we can't finish a Gene Stratton-Porter book without the Dickens-like alter ego. No worries on that point--it is portrayed here in its finest china doll coolness and fragility by the worldly sister and her presumably weak and duped dandy.
