First love
First love always gives unforgettable feelings and moments. Somebody experiences pleasure after the first kiss. Somebody suffers from the parting and cannot forget it. The main love couple of this book was Lux Lisbon and Trip Fontaine. Lux was the youngest sister after Cecilia’s death, but she was first, who met her first love. Lux and Trip even became the king and queen of the school ball, but as it turned out their love was not endless. Lux’s first love could have saved her from death. She loved Trip so much that she was ready to live for his sake. It would have been possible to avoid the suicide. Lux would have refused to commit suicide and dissuaded her sisters. But fate did not give this chance for Lux and destroyed the Lisbon family forever.
Isolation
Isolation from the society is the main reason of the Lisbon girls’ death. It seems that they have plenty of time to love, hate, be disappointed or be happy, meet new friends and enjoy every moment, which can give them happiness. But their isolation destroys everything: their family, future, and dreams. In any case, Mrs. Lisbon is guilty of the daughters' death, because she even forbids them to visit school and go out of doors. This isolation changes their life and only death gives them the eternal freedom.
Religion
The Lisbon girls’ parents are very religious people, and Mrs. Lisbon forbids the girls to drink alcohol, smoke, communicate with boys and other things, which do not benefit the girls. Their mother affirms their wrong and negative deeds are sins, but, as the author insists, there is nothing bad in what they do. Sisters grow up, develop and learn everything about life. Religion turns into the problematic issue for the Lisbon sisters. But to commit suicide is the greatest sin. Cecilia always carries a picture of the Virgin Mary and it seems that she is a believer. But her first suicide changes her point of view about religion. She sins against herself. The girls will never understand the biggest mistake of their life, because they choose death.
