Typical MM romance with all the good ingredients & the right pace: 
 Setting: Australian Outback, at a large Cattle station (ranch). Hence the "red dirt" in the title. 
 Main Characters: Two young men in their twenties. The Australian guy, Charlie, is the heir of the cattle station, a very hard worker and lives in isolation (no social life and self-inflicted dry spell of ... TWO YEARS!). The American student, Tyler, is visiting the Cattle station for one month, and is full of life & uncomplicated. 
 Secondary characters: George and wife Ma, the couple helping Charlie run the station: George is the foreman and Ma is the cook. They've been there before Charlie was born and they love him like the son they don't have. Bobby, the aborigine and great ranch hand & Fish the ranch hand who can drink his weight. 
 Plot: I like the hurdles in the romance: First, they don't know if the other is gay. Second, Charlie is not happy to be gay (blame the late Charlie Sr). Third Tyler is only in Australia for one month. 
 Most emotional moment: (view spoiler)[ An Outback accident happens to one of the MCs and the very secret "holiday romance" is not so secret anymore. (hide spoiler)] 
 Could have been better: The handling of the climax, the last series of confrontation between the two MCs. I wanted to FEEL that their pain was soul-wrenching, their anger all-consuming, I wanted them to be devastated with hopelessness, or hold their breath when they hoped. You know these little things that make you feel tense and pull you up and down when you read. The emotions felt tepid, lukewarm at the end of the book. It was a bit of a let down because until then, the book had been near perfect, the emotions, reactions, characterisation, everything had been spot on. 
 In spite of this flaw, it was a very good read. The characters are likeable & well matched. The romance is well paced, with many cute intimate moments to make you sigh. Oh, and the Ust is good, and topped by really hot sex. It's a shame it's not a series because the setting is really FANTASTIC, and the situation of the two men lets you predicts one or two big conflicts in the future.
