I was able to read Sparks of Light by Janet B. Taylor thanks to a goodreads giveaway of a hardback book and thanks to NetGalley and Houghton Mifflin Harcourt for an arc! Sparks of light continues the story from Into the Dim, the first book in this series. Hope is with Phoebe and their other companions in the Scottish Highlands. Everyone is adjusting to the drastic change in Hope’s mom and the baby she now has. Hope’s boyfriend Bran has gotten away from his mother, Celia, to tell the companions about his mother’s new plan. After Bran reveals Celia’s plan, the Viators make a plan of their own – to travel back to 1895 and visit Nikola Tesla and his discovery. The trip to 1895 causes extreme circumstances for Doug and Hope when they are involuntarily taken to an asylum and treated with the new drug, heroin. Intense and interesting and on the edge-of-your-seat suspense! Hope describes the asylum and its residents in detail. She also reiterates her previous knowledge of asylum history. Morbidly fascinating and scary. As the comrades work to visit Tesla, they encounter atrocities and tragedy in this time traveling adventure worth 5 stars! I am, once again, anxiously awaiting a sequel!
