Can someone summarize in english the phantom of the opera adaption by frank milani and paulette collet

The story of a young chorus girl, Christine - a young talented singer who, with the right training, could become world famous. While rehearsing at the Opera Populaire, where weird and unexplainable things happen, she captures the attention and the heart of The Phantom, or as the Opera Populaire call him...The Opera Ghost. But he is no ghost - he is a disfigured musical genius who has hidden away for years to avoid the cruel stares of strangers. With the Phantoms help, Christine becomes the venue's leading lady, but tragedy awaits as the young soprano has fallen for the charms of handsome noble Viscount Raoul De Chagny, not realizing her Angel of Music is deeply in love with her. Insane with jealousy and unable to see the object of his affection, and ultimately is obsession, in the arms of another man, The Phantom kidnaps Christine - unaware of the lengths Raoul is prepared to go to get her back.
