The Ghosts

The Ghosts by Antonia Barber. mass_market edition. ISBN: 9780671297329.

When Lucy sat in the attic, she thought she heard the sound of voices calling... Thats when she started to believe the rumors in the village that the old house was haunted. But no ghosts appeared - until the day Lucy and her brother Jamie stood in the garden and watched two pale figures, a girl and a boy, coming toward them. That was the beginning of a strange and dangerous friendship between Lucy and Jamie and two children who had died a century before. The ghost children desperately needed their help. But would Lucy and Jamie have the courage to venture into the past - and change the terrible events that had led to murder?
