An epic novel about love and war, set in Regency England and Spain during the Peninsular War (1812-15), by the acclaimed historian and bestselling author of Aristocrats

Tides of War opens in England with the recently married, charmingly unconventional Harriet preparing to say goodbye to her husband, James, as he leaves to join the Duke of Wellington's troops in Spain.

Harriet and James's interwoven stories of love and betrayal propel this sweeping and dramatic novel as it moves between Regency London on the cusp of modernity—a city in love with science, the machine, money—and the shocking violence of war in Spain. With dazzling skill Stella Tillyard explores not only the effects of war on the men at the front but also the freedoms it offers the women left behind. As Harriet befriends the older and protective Kitty, Lady Wellington, her life begins to change in unexpected ways. Meanwhile, James is seduced by the violence of battle, and then by love in Seville.

As the novel moves between war and peace, Spain and London, its large cast of characters includes the serial adulterer and war hero the Duke of Wellington, and the émigrés Nathan Rothschild and Frederic Winsor who will usher in the future, creating a world brightly lit by gaslight where credit and financial speculation rule. Whether describing the daily lives and desires of strong female characters or the horror of battle, Tides of War is set to be the fiction debut of the year.
