The Secret Book Society by Madeline Martin  

You are cordially invited to the Secret Book Society… 
  
London, 1895: Trapped by oppressive marriages and societal expectations, three women receive a mysterious invitation to an afternoon tea at the home of the reclusive Lady Duxbury. Beneath the genteel facade of the gathering lies a secret book club—a sanctuary where they can discover freedom, sisterhood, and the courage to rewrite their stories. 
  
Eleanor Clarke, a devoted mother suffocating under the tyranny of her husband. Rose Wharton, a transplanted American dollar princess struggling to fit the mold of an aristocratic wife. Lavinia Cavendish, an artistic young woman haunted by a dangerous family secret. All are drawn to the enigmatic Lady Duxbury, a thrice-widowed countess whose husbands’ untimely deaths have sparked whispers of murder. 
  
As the women form deep, heartwarming friendships, they uncover secrets about their marriages, their pasts, and the risks they face. Their courage is their only weapon in the oppressive world that has kept them silent, but when secrets are deadly, one misstep could cost them everything. 

Clown Town by Mick Herron  

Spies lie. They betray. It's what they do. 

Slow horse River Cartwright is waiting to be passed fit for work. With time to kill, and with his grandfather - a legendary former spy - long dead, River investigates the secrets of the old man's library, and a mysteriously missing book. 

Regent's Park's First Desk, Diana Taverner, doesn't appreciate threats. So when those involved in a covert operation during the height of the Troubles threaten to expose the ugly side of state security, Taverner turns blackmail into opportunity. 

Over at Slough House, the repository for failed spies, Catherine Standish just wants everyone to play nice. But as far as Jackson Lamb is concerned, the slow horses should all be at their desks. 

Because when Taverner starts plotting mischief people get hurt, and Lamb has no plans to send in the clowns. On the other hand, if the clowns ignore his instructions and fool around, any harm that befalls them is hardly his fault. 

But they're his clowns. And if they don't all come home, there'll be a reckoning.
