Not only does this supposedly 'edited' book (purported by Rosa Sophia) use full stops instead of commas for dialogue punctuation, it can't even get the name of the musical or the name of the composer correct.
There's a quote (supposedly) taken from the 1986 musical The Phantom of the Opera at the beginning of the book:
"Close your eyes for your eyes can only tell the truth
and the truth isn't what you want to see...
In the dark it is easy to pretend
that the truth is what it ought to be."
Attributed to Andrew Lloyd Weber.
It's actually Webber.
It also claims the quote is from "The Phantom", which it's not. It's not even from The Phantom of the Opera composed by Andrew Lloyd Webber. It's from the alternate lyrics of the song Music of the Night (yes, originally from the musical), often sung and recorded by popular singers, not the musical. For the real version, find any cast recording (though I recommend the original London), and Webber's ex-wife Sarah Brightman (the original Christine) recorded the correct version on her The Andrew Lloyd Webber Collection and Surrender albums.
The show version is thus:
"Close your eyes and surrender to your darkest dreams.
Purge your thoughts of the life you knew before.
Close your eyes, let your spirit start to soar,
And you'll live as you've never lived before."
Even then, Andrew Lloyd Webber wrote the music, not the lyrics. Richard Stilgoe and Charles Hart wrote the lyrics, though I'm not sure how one correctly attributed lyrics in this situation (being the alternate lyrics, of whom I do not know the author - Webber himself very may well be the author of those particular lyrics, though they are not from the musical they are attributed to).
Not only is this supposedly edited book obviously not, the author can't even get the name of the composer correct, the show correct, or even attribute the correct lyrics.
