The House at the End of the Sea

"Saffi doesn't want her new life, living with her dad, little brother and old-fashioned grandparents in their B&B by the sea. She is grieving for her mum and longs for things to go back to normal. But this new home is anything but normal: the walls change colour, a face appears in the mirror, and the pantry is suddenly filled with fancy food. When a party of extraordinary visitors arrive at midnight, Saffi begins to realise that her family has a dark, magical secret. It will take all her bravery to discover the truth and find a way into another world..."--Amazon.com.
