After discovering she’s an heiress to a billion-dollar corporation, seventeen-year-old Liliana finds herself at a new boarding school where she must navigate secret societies and a deadly competition. Not to mention two handsome boys.
In the wake of her mother’s death, Liliana Chamberlain’s estranged (and very wealthy) grandparents swoop in. Or their lawyer does. Her grandparents aren’t ready to meet her, but they want her to have the life her mother walked away from, starting with Westdale Academy, the elite boarding school her mother attended. It should be a Cinderella dream come true, but Lili has serious misgivings. Yet she doesn’t have a choice, being under eighteen and dead broke.Westdale Academy is a school of secrets as well as intriguing classmates, including Hollywood golden boy Theo Dubois and the mysterious Maddox Moreno. As she gets to know them all, Lili realizes there’s more to the school than elite-level networking. Something deadly.
For the new girl at school, investigating the deaths of past students — including Maddox’s own sister — is a very dangerous game. Do those deaths have something to do with why her mother fled Westdale at the cost of her inheritance?
When a fun night out turns bloody, Theo is the prime suspect, and Liliana must race against time to connect the past with the present and discover the truth behind her inheritance.
While YA thrillers are not my typical jam, I had no hesitation when it came to picking up this newest book by author Kelley Armstrong. A Deadly Inheritance provides the twisty, complicated plot and fascinating characters that are hallmarks of her writing, and delivers a thrilling drama with enough devious clues to make a reader’s head spin.
In A Deadly Inheritance, 17-year-old Liliana is desperately selling everything not nailed down in her shabby apartment in order to keep paying the rent and keep up appearances. Orphaned after her mother’s death, Liliana just has to fake it a few more months until she turns 18 and can avoid the foster system. A gifted student, she already has a free ride to college waiting for her, if she can only make it through to her high school graduation and legal adulthood.
All that seems to come crashing down when Child Protective Services comes knocking at her door — but the CPS representative is stymied by the appearance of a lawyer who claims to speak on Liliana’s behalf. In short order, a huge secret is revealed: Liliana is actually the granddaughter of the Chamberlains of Chamberlain Enterprises, and heiress to a fortune in the billions. In the blink of an eye, Liliana is whisked away from her former life and enrolled at Westdale Academy, a boarding school for the children of the ultra rich and powerful, where having the right allies and connections is the most sought-after prize.
At Westdale, Liliana is wooed by the members of the Lilith Society, whose members are the school’s top female students. She’s also drawn to two very different boys: Theo, the golden-child son of Hollywood power players, and Maddox, an emotionally complex young man descended from a tech fortune, whose family’s past contains its own share of trauma.
Liliana settles into her new environment and begins to form deep connections, but there’s immediate danger as well. Someone tries breaking into her room. a fellow student tries to push her down the basement stairs, and at an off-campus event, she’s attacked and wounded. Why is someone trying to hurt Liliana, and is this connected to mysterious events from Westdale’s secretive history?
A Deadly Inheritance is an absolute page-turner, as the clues come fast and furious, with new suspects and theories around every corner. Something very bad is going on… but the answers will keep you guessing right up until the final chapter. I know I had plenty of theories… and most of them turned out to be dead wrong!
I really enjoyed Liliana as a lead character. As someone raised with no knowledge of her mother’s true past, she has no idea that she comes from money, and therefore has none of the snobbishness or entitlement so often seen in stories about privileged teens. Liliana’s entry into the world of Westdale is shown through her eyes, so we get to experience both her wonder and confusion at the wealth around her and the casual acceptance of a world of instant, constant luxury.
There’s a romantic subplot that is not what you’d expect, and I ended up really enjoying it. I can’t say I’ve come across this particular approach in YA fiction before… and that’s about all I’ll say about it, but trust me, it’s very well-written, innovative, and fun to see unfolding.
The mystery/thriller aspects are very well constructed. There are just enough clues to keep a reader guessing, but never enough to be obvious. When the answers do come, they require full concentration — the plot is clever and intricate and full of sharp little details to throw us off course.
I did have a few minor quibbles — just certain details about Liliana’s earlier life and how her new status as an heiress unfolded that felt glossed over and fully explained. In an adult novel, these elements probably would have felt more substantial, and the lack of detail might have been less easily overlooked. Here, with a YA vibe, the missing details can be more readily pushed aside in favor of the focus on Liliana’s experiences and feelings. It works!
I’ve read quite a bit of Kelley’s Armstrong recent novels for adults, including the outstanding Rockton and Haven’s Rock series, several terrific stand-alone horror novels, and even a couple of rom-coms. A Deadly Inheritance is my first experience with her young adult writing. I’m happy to confirm that it was just as good as I’d expected!
While marketed as YA fiction, A Deadly Inheritance makes a great read for adults too. I really enjoyed this thriller, and highly recommend it.
