The Puppet Show?

I haven't watched this movie, but after reading the reviews it reminds me very much of the novel The Puppet Show by Patrick Redmond.

Has anyone who has watched this movie and read this book been able to draw any parallels?

Here's the official synopsis of the book, although it is much more complex than appears below:

"Michael Turner is still fighting the demons of his childhood. He grew up alone; an orphan lost in a maze of institutions and foster homes, surviving on dreams of success, and of finding a place where he was wanted and could belong.

Now, in his early twenties, he is at last beginning to escape his past. He has a loving fiancee and is taking the first steps in a promising legal career. And when, unexpectedly, a powerful father figure enters his life, it seems that all Michael's childhood dreams are being realised.

But dreams come with a price. Michael has allowed a dangerous cuckoo to enter the nest. One who is plagued by his own demons, who can manipulate the needs and vulnerabilities of others to dreadful effect..."
