A Ghost in the House by Betty Ren Wright, 1991.

At first, Sarah Prescott enjoyed her family’s new house.  The house wasn’t really new.  Other members of Sarah’s family had lived there before, but it was the first place where Sarah hadn’t had to share a room with her younger brother.  Then, Sarah’s Great-Aunt Margaret came to live with them, and everything changed, in more ways than one.

Aunt Margaret is the one who actually owns the house where Sarah and her family are living.  She’s is elderly and sick and has been living in a nursing home.  The rent that Sarah’s parents pay her pays for her care at the nursing home.  However, Aunt Margaret has been doing a little better, and she would like to come and live with the family.  Having her move in with the family would not only be good for her but for them because Sarah’s father has been in and out of work, and Aunt Margaret wouldn’t charge them rent or at least not much if they all lived together and they helped to take care of her.  However, it would mean some sacrifice on Sarah’s part.

Aunt Margaret had once slept in the beautiful room that Sarah has been using, and Sarah must give it up for her now that she will be living with them.  It’s difficult for her to deal with, but Sarah is also restricted on when she can have friends over because Aunt Margaret needs her rest, and the family’s lack of money means that Sarah won’t be able to go to the concert that everyone at school as been talking about.  These family problems and teen angst could be bad enough, but from the moment that Aunt Margaret moves in, strange and frightening things start happening that only Sarah and her aunt ever witness.

Whenever Sarah and Aunt Margaret are alone in the house, rooms get cold, and Sarah hears weird things like footsteps walking around when no one should be there and a girl’s voice singing that particularly unnerves her aunt.  Sometimes, Aunt Margaret’s things are moved around or broken, and there is something mysterious about an old painting that has been in the house for years.  Over time, Sarah begins to notice that the painting darkens, and sometimes she can see a man in the painting who wasn’t there before.  The presence of the painting also upsets Aunt Margaret, although she refuses to say why.  Although Aunt Margaret at first suspects that Sarah is the cause of some of the weird things that are happening, Aunt Margaret is the actual cause, and she is afraid to admit the dark secret from her past that has come back to haunt her.

A long time ago, when she was young, Aunt Margaret had a best friend called Anne, whose father painted the mysterious painting.  Anne had a very unhappy home life, and when the opportunity arose for Margaret’s family to adopt her, Margaret wasn’t sure if she wanted to share her home with her friend, although she cared for her a great deal.  Because of her hesitation, her parents decided not to adopt Anne.  In her old age, she admits that she was a spoiled girl.  Unfortunately, her friend went to live with other relatives and ended up dying in a fire, so Margaret never had a chance to make things right with her.  Although Anne’s death was a freak accident, Margaret felt guilty because Anne would have lived if her family had adopted her.  Anne’s father also blamed Margaret and her family for not doing more for his daughter, although it was his drunkenness and violence that ruined his home life and led him to give up his daughter in the first place.  Before he died, he threatened revenge against the family in some way.  Now, his vengeful spirit has found a way to use the old painting to reach Margaret once again, and unless Sarah can find a way to stop him, he will make sure that Margaret joins Anne in death . . . and possibly Sarah, too.  However, there is also Anne’s spirit to consider.  In life, Anne was the only person who ever stood up to her father.  Would she be willing to do it one more time for Margaret’s sake?

Part of the story is about being willing to sacrifice for the ones you love.  Years ago, Margaret hesitated to give up some of her pampered life for her best friend, and she regretted it forever after.  Sarah also comes to see how her earlier worries about giving up her room and about sleepovers and concerts were petty when compared to helping a relative who loves her.  She also sees how it’s important to do the right thing when there’s time because sometimes there is no opportunity to do it later.

In a way, I felt like the problem was solved rather easily, but there were some pretty scary incidents in the story and a failed attempt to get rid of the painting that brought some suspense.
