A Bookaholic review of Riley Sager’s slow-burn thriller with one of his boldest twists
Review by Maria Antokas
I finally picked up The House Across the Lake by Riley Sager – a backlist thriller I’d somehow managed to miss – and let me just say… this one takes its time getting out of the emotional starting blocks. The story opens with Casey Fletcher, a once-famous actress who has essentially been exiled to her family’s lake house after her husband’s tragic drowning. Yes. The same lake house. On the same lake. If this was her therapist’s idea, someone needs their license reviewed immediately.
For much of the first half, the narrative feels weighed down by long passages of grief and escalating bourbon-and-vodka-fueled self-destruction. Casey has lost her acting career, become tabloid fodder, and spends her days in a haze of regret and very questionable decision-making. It doesn’t make the book unbearable – but it does slow the momentum while we wait for the mystery engine to properly start.
Things finally get interesting when, during one of her many binocular vigils across the lake, Casey spots what appears to be a body floating in the water. The “body” turns out to be Katherine – a stunning supermodel married to a tech billionaire living directly across from her – and the two form a quick, slightly uneasy friendship. Then Katherine disappears. Naturally.
Suspicion bounces around like a caffeinated squirrel. The controlling husband looks guilty. The handsome handyman with a shadowy past looks guilty. Honestly, even the lake starts to feel guilty. Meanwhile Casey continues her full-time career as Chief Snooping Officer, armed with binoculars so powerful they seem capable of penetrating walls, darkness, and possibly national security protocols.
Where the novel truly grabbed me was when Casey begins connecting unsettling dots involving other missing women in the area. At that point, the story shifts into fourth gear and refuses to slow down. And then – without warning – Riley Sager unleashes a twist so wild I actually said “Whaaaaaat?” out loud and startled my sleeping husband. It’s not just a murder mystery anymore. It’s a full narrative detonation.
Credit where it’s due: Sager absolutely sticks the landing. The ending is bold, unsettling, and just ambiguous enough to leave you staring at the last page wondering whether anyone really got a happy ending… or whether the lake is still keeping secrets.
⭐ Bookaholic Verdict: A grief-heavy slow build that explodes into one of the most unexpected twists in recent thriller memory. Definitely worth the ride.
