I have read nearly all of a Shalini's books and loved them all. I still have two I've yet to read but plan to in the near future. They are on a very long TBR list!
Shalini mainly writes psychological thrillers but she has also written a supernatural series, the Hidden series and also a dystopian series, the Outside series and I enjoyed both but it's the thrillers I enjoyed the most.
In particular The Child Next Door, The Secret Mother, The Best Friend and The Millionaire's wife. I'm looking forward to her upcoming release The Silent Sister.
Her other great books are The Girl from the Sea, and the two I've yet to read A Shirtful of Frogs and The Ghost of Nan Clarks Lane.
If you love page turning thrillers then read Shalini's work, you won't be disappointed.
