The Infinite Minute (The Magic Hour #2)

As Ailsa reaches her thirteenth birthday, her celebration is dampened by a school rumour that has caused a huge fall out with her best friend. Worse than the rumour we'll call 'The terrible thing', the Brollachan monster is at large in Edinburgh and it's causing chaos. After all, when something from another world appears in this one, it's only natural that things become unbalanced. Time is worse than ever before. Mornings are evenings and all clocks read different times of the day. Nobody knows where they are supposed to be. The only thing for Ailsa to do is bravely enter Middlemarket, the immortal world behind Edinburgh and find a way to lure the Brollachan back to where it belongs. But as the days keep repeating themselves, Ailsa is stuck in a time loop like no other, and the terrible thing soon becomes the terrible things.
