A Chase In Time

From multi-award-winning author Sally Nicholls, A Chase In Time is the first in a brilliant time-slip adventure series for 9+ readers, beautifully illustrated by Brett Hellquist.
The old gilt-edged mirror has hung in Alex's aunt's house for as long as he can remember. Alex hardly notices it, until the day he and his sister are pulled through the mirror, back into 1912. It's the same house, but a very different place to live, and the people they meet need their help.
Soon they're caught up in car chases and treasure hunts as they race to find a priceless golden cup - but will they ever be able to return to their own time?
