Bloodline opens on the battlefields in France during the First World War. John Shaw is to join the regiment of Captain Quincy Harker, another fellow Romanian who is fighting for England. The book is told through a series of letters and diary entries. One soon realizes that Captain Harker was no common officer, but was, in fact, a vampire. John Shaw struggles with the things he witnesses Captain Harker do to the enemy. He details all of this in his journal, but falls ill with delusions and is returned to England, where a young woman named Mary Shaw nurses him back to health. But, she also reads his journal and becomes very suspicious about the Captain and what had happened during the war. Lilly, John’s sister, none the wiser to the ways of Captain Harker, invites him to live with her while John recuperates because she is so grateful that John’s life was spared on the battlefield. Captain Harker and Lilly fall in love, while Mary Shaw and John do likewise. Mary is very nervous about the developing relationship between Lilly, because she believes most certainly that Captain Harker is a vampire. Lilly and Captain Harker decide to travel back to Romania and be wed in Transylvania at his family’s castle, the old castle of Count Dracula. Finally, John realizes that his own and Mary’s suspicions are correct, Captain Harker is a vampire. They set out to save Lilly from her certain death and entry into the world of vampires, and rid the world of vampires. What John and Mary discover is bone-chilling, and these discoveries begin when John realizes he is oddly powerful over the beasts in the wild. The battles that ensue against vampires within the Castle are wildly entertaining and suspenseful. There are many unexpected twists to the plot, and the story ends with no doubt that there will be a sequel.
, I think that this book is best for older teenagers, 16+.
