Blue Moon. FIUL TIMPULUI.

Marcus MacNeil learns the cost of life as a vampire. He is a young doctor from Massachusetts. During the American Revolution, he meets Matthew de Clermont. Matthew offers him a way to live past death. It also frees him from his strict Puritan roots. Marcus accepts, but his new family has its own rules. He believes in freedom, equal rights and brotherhood. These views clash with the de Clermont family's old ways and duties.

In Paris today, Marcus's love plans to become a vampire too. Her name is Phoebe Taylor, and she works at Sotheby's auction house. The process has changed since Marcus went through it. Yet it still asks much of those who leave human life behind. Parts of his past may come back to threaten them both.

This fantasy romance by Deborah Harkness joins love with family strife. It asks how people can change customs that seem set for all time. Fans of tales of the supernatural will find links to Harkness's trilogy, Cartea pierdută a vrăjitoarelor. This book is the fourth in that series.

The story shows how the American and French revolutions were alike. Vampires watch these events unfold. Lafayette, Benjamin Franklin and Thomas Paine also appear with them.
