Books like Silent Girl by Tess Gerritsen

After a ski trip in Wyoming turns deadly, Boston medical examiner Maura Isles disappears in a blizzard, driving her friend, Boston homicide detective Jane Rizzoli, into a frantic search that uncovers a sinister, snow‑shrouded village called Kingdom Come.

Gina Royal is the definition of average--a shy Midwestern housewife with a happy marriage and two adorable children. But when a car accident reveals her husband's secret life as a serial killer, she must remake herself as Gwen Proctor--the ultimate warrior mom. With her ex now in prison, Gwen has finally found refuge in a new home on remote Stillhouse Lake. Though still the target of stalkers and Internet trolls who think she had something to do with her husband's crimes, Gwen dares to think her kids can finally grow up in peace. But just when she's starting to feel at ease in her new identity, a body turns up in the lake--and threatening letters start arriving from an all-too-familiar address. Gwen Proctor must keep friends close and enemies at bay to avoid being exposed--or watch her kids fall victim to a killer who takes pleasure in tormenting her. One thing is certain: she's learned how to fight evil. And she'll never stop.

Two timelines converge in Boston as a modern investigator and a 19th‑century medical student race to solve a series of murders tied to a buried skull and a kidnapped baby.

Boston medical examiner Maura Isles and Detective Jane Rizzoli are called to investigate a serial murder that links them to controversial celebrity psychiatrist Joyce O'Donnell-Jane and the Mephisto Club.

"I very much need to be dead." These are the chilling last words left by a man who had everything to live for but took his own life. In the void that remains stands his widow, FBI agent Jane Hawk, surrounded by questions destined to go unanswered unless she does what all the grief and fury inside her demand: Find the truth, no matter what. People of talent and accomplishment, people seemingly happy and sound of mind, have recently been committing suicide in surprising numbers. A disturbing pattern is beginning to emerge. Jane is determined to give up everything to find out why. And if that means going rogue and becoming America's Most Wanted, then so be it. Those arrayed against her are legion, and devoted to protecting something profoundly important-or terrifying-enough to exterminate any and all in their way. But Jane is as clever as these enemies are cold-blooded, as relentless as they are ruthless. And she is driven by a righteous rage they can never comprehend. Because it is born of love.

Violinist Julia Ansdell finds a mysterious piece of music that transforms her daughter in ways she cannot explain, leading her on a hunt across Italy to reveal a deadly family secret.
