City of darkness and light
(Book)

Series numeration from NoveList.

Molly and Daniel Sullivan are settling happily into the new routines of parenthood, but their domestic bliss is shattered when a gang retaliates against Daniel after he makes a big arrest. Daniel wants his family safely out of New York as soon as possible. Knowing she needs to protect their young son Liam, Molly agrees to take him on the long journey to Paris to stay with her friends Sid and Gus, who are studying art in the City of Light. But upon arriving in Paris, nothing goes as planned. Sid and Gus are nowhere to be found, and Molly's search for them leads her to the doorstep of a renowned Impressionist artist, whom she's horrified to learn has just been murdered. The longer Molly goes without finding her friends, and the more she learns about the painter's death, the more she starts to wonder if she and Liam might be in even more danger in Paris than they were at home. As Impressionism gives way to Fauvism and Cubism and the Dreyfus affair rocks France, Molly races through Paris to outsmart a killer.
