My father and I just finished Winterhouse by Ben Guterson, the first of the Winterhouse trilogy.
Riddles and puzzles, magic and lore, together make a book that is never a bore; and for Elizabeth and Freddy words are the key to unraveling a generational mystery. But enemies abound, and a hatred that is a curse, which along with a blessing is wrapped in cipher and verse. So they searched for clues and made a few mistakes, plus a feeling that causes objects to shake. But the Falls family did not fall but has stood, for in the end Elizabeth did choose the good. Yet though she did in this adventure prevail, we are far from done with the Winterhouse tale.
