Goodreads Synopsis: 

No visitors. No nights spent away from the apartment. No disturbing the other residents, all of whom are rich or famous or both. These are the only rules for Jules Larsen’s new job as an apartment sitter at the Bartholomew, one of Manhattan’s most high-profile and mysterious buildings. Recently heartbroken and just plain broke, Jules is taken in by the splendor of her surroundings and accepts the terms, ready to leave her past life behind.

As she gets to know the residents and staff of the Bartholomew, Jules finds herself drawn to fellow apartment sitter Ingrid, who comfortingly, disturbingly reminds her of the sister she lost eight years ago. When Ingrid confides that the Bartholomew is not what it seems and the dark history hidden beneath its gleaming facade is starting to frighten her, Jules brushes it off as a harmless ghost story—until the next day, when Ingrid disappears.

Searching for the truth about Ingrid’s disappearance, Jules digs deeper into the Bartholomew’s dark past and into the secrets kept within its walls. Her discovery that Ingrid is not the first apartment sitter to go missing at the Bartholomew pits Jules against the clock as she races to unmask a killer, expose the building’s hidden past, and escape the Bartholomew before her temporary status becomes permanent.

Genre: Thriller
My Rating: ****** (5 of 5 Stars)

There is a lesson to be learned here – if it seems too good to be true, it probably is! Jules’ good friend Chloe tries to warn her of this when she gets the ridiculously high-paying (for almost no work) job apartment sitting in the exclusive Bartholomew building. Desperate to earn money, however,  Jules refuses to listen to reason.

Lock Every Door is a nail-biting, edge-of-your-seat, what-is-going-on-here thriller. Every time I thought I had some idea about what was happening at the Bartholomew, something would happen to prove me wrong and I was completely surprised to learn the truth. Jules was a believable, likable heroine which made me more concerned for her safety and made it harder to put the book down. I never knew who she should trust (and neither did Jules) or what was coming next, and I loved every minute of it.
