i need help finding information about the book in the time of butterflies please help :/

Here's a synopsis from
Wikipedia:

This is the story of the four Mirabal sisters during the
dictatorship of Rafael Trujillo. The sisters make a political commitment to overthrow
the Trujillo regime. They are harassed, persecuted, and imprisoned, their family suffers
retaliation from the Military Intelligence Service, and they are eventually awarded
awards for their awesome leadership. The book presents the perspective of each,
including the one surviving sister, Dede. Throughout the book the events leading up to
each sisters political awakening are discussed.
The story begins when the
author, Julia Alvarez, visits Dede Mirabal to discuss the tragic story of her sisters.
Although Dede at first refuses, she eventually tells her sisters' tale. She explains how
Minerva had a dream of going to a school, which was unusual for farmers' daughters. When
she eventually convinced her father to allow her go, Minerva meets a girl, Sinita, who
later became one of her best friends. Sinita eventually confided in Minerva the truth
about Trujillo - that their "glorious" leader was a killer.
During the time
Minerva was in school, other events help bring the dictator's secrets to light. One of
Minerva's friends was taken by Trujillo to carry his child, and was then exiled from the
Dominican Republic to escape the wrath of Trujillo's wife.
Years later,
Minerva was invited to a party held by Trujillo in Santo Domingo. When he repeatedly
tried to court her, she slapped him, putting her family in jeopardy. The Mirabal sisters
and their husbands were participants in the June 14 political group, which operated
through illegal gatherings in Patria Mirabal's house, where they discussed their plot
against Trujillo. The members of the group used false names, with the Mirabal sisters
all referred to as "Butterfly", followed by a number to indicate the individual
sister.
As punishment for their political activities, Trujillo orders three of
the sisters be killed on Puerto Plata Road, with their driver Rufino, while returning
from visiting their husbands in jail. The women and driver are beaten to death and later
their vehicle and bodies are dumped off a cliff in order to make their deaths look like
an accident.
