"Infinit" is a book series consisting of seven sequels, written by the Russian writer Mariia Nova, "The last bridge of Sam" is the first part of the series.The world of Nova is a place of numerous adventures about 7 fantastic Worlds for everyone who enters, and author's master descriptive skills are a relentless source of stimulants and pleasure for children, but also for some of the older companions through the adventures of life. As said by Nova herself, she got the vision of Nova World and its magic when she was only twelve, and then, almost twenty years later, she decided and promised to herself that she will share this interesting story with the World.Although the stories from Infinit tells us adventures of other worlds and their inhabitants, rulers, their festivities and troubles as well, the main motif of the story is a fight between good and evil.The display of that ultimate battle is the sole purpose of author's series, and for that evil to be conquered, the excessive amount of effort and knowledge is required, as well as the special ability to observe the moral, value and positivity by using the inner eye. Nova finds that ability as an irreplaceable consistency of life, recognizable within children and adults as well, together with the ability to cope and fighting against all the opposites of good.Also, the base of this Series is its self-existence in which everything is arguable and it seems exactly the way as it is. Human's ability to make the various choices is relevant for her life, and mostly for her feelings and inner urges. Exactly that is the reason why this accentuation of conscience is relevant for the reader's mind, especially for children because this type of conscience requires a fight, similar to the ones that creatures of Nova's World are fighting.The orphan, teenager girl - Sam, who's adventures are followed after entering the Nova's World through the bridges, is entering the magical worlds she has to save from the Dark Force - Reptilian, who conquered one world after another in that time.
