Conjuration - Rivers Sisters, #2

Heather Rivers is brilliant. Academically gifted, she spends her days studying the stars and looking for a connection between her father's disappearance and the heavens. The massive solar system? No problem. People? Not a fan. The multitude of voices in her head? Over it. Montgomery James makes a living carving out places for other people. He can draft and design down to the last inch by simply looking at a space.
He's a man who follows his instincts, and those are leading him directly to Heather. But she would rather they lead him to someone else, anyone else, because her priorities don't include a smug mortal who knows nothing of curses and witches and dragons. Except the voices are becoming louder, and Heather's control is slipping. She disappears while searching for answers, and Montgomery pleads with her family to let him help.
He's used his intuition to avoid trouble his entire life. But these stakes are higher, and he won't be able to avoid what's coming for them.
