What happens in the book Sweet Deceit by kate Brian be descriptive please?
SPOILER ALERT
Ariana, Kaitlynn, and a few of their friends are faced with
tasks to complete as their way in to a secret society. At one
question and answer session, Kaitlynn refuses to answer questions
about her family, so, Lexa as one of the members, hires a private
investigater to look into Kaitlynn's past. Ariana, knowing that
information found on Kaitlynn would in turn hurt Ariana herself,
she tells Kaitlynn about the PI. Kaitlynn tells Ariana that she can
do this, and, on the night of Lexa's Halloween Party, when she
leaves the party to meet with the PI, "Lillian" follows her. Kate
Brian, writing an unexpected twist, narrates Ariana trailing behind
Kaitlynn. She reaches the house to find Kaitlynn and Lexa in a
fight. Ariana kills Kaitlynn and plays hero to Lexa, swearing the
girl to secrecy. The girls bury Kaitlynn's body and Lexa gives
Ariana a free pass into the Secret Society. However, when they go
to the party to try and pretend like nothing happened Kiran is
there and obviously recognises Ariana, and Ariana ends up pushing
her over a bridge into the water.
