Timecatcher — Marie-Louise Fitzpatrick

The old Dublin Button Factory hides a secret. There, Jessie meets a boy who walks through walls but can't remember his own name, and discovers the Timecatcher, a swirling, powerful Magic, which every seven years reveals the past, both good and bad, in a jumble of days. The Timecatcher is about to open now, and there are those who will go to any lengths to control it. Jessie and her friends - both ghosts and human - must stop them, before it's too late.

A fast-paced ghostly adventure, sparkling with humour and heart.
