Lights All Night Long by Lydia Fitzpatrick
'Lights All Night Long' offers an interesting outsider perspective. Ilya, a Russian exchange student, arrives in Louisiana anxious about his brother's recent arrest for murder. He's unwilling to confide in his cheerful host family, and must dwell on his doubts alone, until he makes an unexpected ally in the family's teenage daughter.
Alternating between Ilya's childhood in Russia and his experiences in the United States, Ilya struggles to reconcile the memory of his brother with the horrible murders that haunted his home. Across a continent and an ocean he struggles to find evidence to redeem his brother, and himself, too.
Fitzpatrick expertly holds onto the tension of the story, seamlessly tying together the different timelines and never loosens her emotional grip on the reader.
