My favorite book is «Gone with the wind». This novel was written by Margaret Mitchell in 1936. The life of the lady -Scarlett O'Hara is shown* in this book. Almost all men have fallen in love with her and she uses* it. In her dreams she loved Ashley Wilkes, who was married to Melanie Hamilton. Scarlett was married thrice / three times*. Every marriage gave her an advantage*. After the American Civil War Scarlett’s house was robbed, but she recovered all by herself. When Melanie died, Scarlett understood that she didn’t love Ashley. She loves Rett Battler, who couldn’t wait for her. But he loved her too. My favorite person in this novel is Melanie Hamilton. She is lovely and a kind woman. Melanie has always seen the good in people. She has never believed to gossip. Melanie has taken in (her house)* all those in need. She was a weak lady, but very brave. Melanie is the image of the ideal person. This novel is about life, love and hardships. In 1991 Alexandra Ripley continued to write the novel*.

used vs. uses = Because this is a book/ novel, language usage changes, past tense --> to present progressive. HOWEVER, this is my view, other people may chose 'used' instead of 'uses'.

Thrice = This is correct, however it is very poetic and not used in daily life. Three times is good. People will still understand 'thrice' :)

"Every her marriage had the advantage for her" = Is not grammatical. 'her' is not needed, based on the previous sentence, you do not need to write again 'her marriage' as it is already implied. 

"Melanie has taken to her house all those in need" = is understandable, but not grammatical. You could write the sentence like this: "Melanie took to her home, all those in need". This makes sense. HOWEVER, in English, saying 'I/he/she took them in, had taken them in" without 'her house' makes perfect sense. Usually, if someone is 'taken in' you do not have to specify 'where' unless it is not obvious. For example: "the old lady took in the stray cat" [we can assume, the old lady will care for the cat, in her home]. "The police took the man in" [the police have taken someone to the police station]. 

I hope this makes sense. If not, just ask :)
