Aluminium oxide is an amphoteric oxide of aluminium with the chemical formula Al2O3. It is also commonly referred to as alumina, corundum, sapphire, ruby, alundum or aloxite in the mining, ceramic and materials science communities. It is produced by the Bayer process from bauxite. Its most significant use is in the production of aluminium metal, although it is also used as an abrasive due to its hardness and as a refractory material due to its high melting point.
New York reporter Paige MacKenzie has a hidden motive when she heads to the small town of Timberton, Montana. Assigned to research the area's unique Yogo sapphires for the Manhattan Post, she hopes to reconnect romantically with handsome cowboy Jake Norris. The local gem gallery offers the material needed for the article, but the discovery of an old diary, hidden inside the wall of a historic hotel, soon sends her on a detour into the underworld of art and deception. Each of the town's residents holds a key to untangling more than one long-buried secret, from the hippie chick owner of a new age café to the mute homeless man in the town park. As the worlds of western art and sapphire mining collide, Paige finds herself juggling research, romance and danger. With stolen sapphires and shady characters thrown into the mix, will Paige escape the consequences of her own curiosity?
