Lelakatolt ajtók, szokatlan fények, mutáns csótányok. Nate lakásával valami nincs rendben. De a gondolatait most más k?ti le. Utálja a munkáját, a bankszámlája lassan kimerül, és még barátn?je sincs. Elképzelni sem tudja, mit vár az életét?l. ?j lakása nem éppen ideális, de legalább élhet?, és megengedheti magának. A bérleti díj egészen alacsony, a házkezel? cég ügyn?ke szuperbarátságos, és a rendellenességek inkább csak idegesít?ek, mint nyugtalanítóak. Egészen addig, amíg a férfi nem találkozik Mandyvel, a szomszédjával, és fel nem fedezi a lány lakásának furcsaságait. ?s a másik szomszédjáét, Xela-ét . ?s Tim és Veek lakásáét is. Merthogy a régi, Los Angeles-i téglaépület minden egyes bérlakása szolgál némi rejtéllyel. Olyan rejtélyekkel, amelyeknek a t?rténete t?bb mint száz évvel korábbra nyúlik vissza. Némelyik furcsaság szembe?tl?, míg másokat zárt ajtók rejtenek el a kíváncsi tekintetek el?l. Viszont ha e kül?n?s rejtélyek ?sszeadódnak, az akár a véget is jelentheti Nate és barátai számára. Vagy az egész világ számára…

Owen élete fenekestül felfordul, amikor apja, akit a fiú meggy?z?dése szerint ártatlanul ítéltek el, meghal a b?rt?nben. Monroe, a fiú iskolájának informatikusa felajánlja neki, hogy egy Animus használatával lehet?vé teszi Owen számára, hogy tisztázza apja nevét. Az eszk?z segítségével ugyanis feltárhatja a saját DNS-ében rejl? genetikus emlékeket. ?m Owen nagyobb fába vágta a fejszéjét, mint hitte. A szimuláció alatt ugyanis felfedez egy ?si és nagy hatalmú, rég elveszettnek hitt relikviát – az ?denszigonyt. Két rivális titkos szervezet, az Orgyilkos Testvériség és a Templomos Rend semmit?l sem riad vissza, hogy megszerezze ezt az ereklyét. Owen számára hamarosan nyilvánvalóvá válik, hogy csak úgy menekülhet meg, ha ? találja meg el?sz?r a Szigonyt. Monroe irányítása alatt Owen és néhány másik fiatal egy olyan szimulációba lépnek be, amely a DNS-eikben lév? k?z?s emlékeken alapul: az 1863-as New York-i felkelés idejébe térnek vissza. Owen és társai súlyos kihívásokkal kerülnek szembe a forrongó város utcáin, ott megélt tapasztalatiknak pedig hosszú távú k?vetkezményei lesznek a jelenben. A t?bbsz?r?sen díjnyertes Matthew J. Kirby trilógiájában egy az Assassin’s Creed világában játszódó teljesen új t?rténetet ismerhetünk meg, amely szorosan illeszkedik a kánonba, számtalan utalással a játékokra és a decemberben mozikba kerül? filmre.

Miután John és Brooke magára maradt, városról városra stoppolva vadásznak Amerika k?zép-nyugati részén a még megmaradt utolsó Sorvadtakra. Csakhogy a Sorvadtak is vadásznak rájuk, ráadásul az FBI is a nyomukban van. Minden újabb várossal, minden újabb kamionos pihen?vel, minden újabb autópályával egyre k?zelebb kerülnek egy olyan kegyetlen gyilkoshoz, akire John semmilyen jól bejáratott analitikus és el?rejelz? módszere nem alkalmazható. K?zben Brooke meghasadt pszichéje az elméjén osztozó t?bb százezer halott személyiségt?l túlterhelve tántorog az ?sszeomlás peremén. Hol birtokában van szellemi képességeinek, hol nem, és minden nap új nevek, gondolatok és emlékek t?rnek felszínre benne, mígnem felbukkan az a személyiség, akire John végképp nem számított: Senki utolsó áldozata, csapdába esve John egyetlen megmaradt barátjának testében.

A New York Times bestseller Hollóárnyék-trilógia Magyarországon is nagy sikert elért szerz?jének új sorozata! TARTALOM: Véráldottak – olyan férfiak és n?k, akik a vad sárkányok véréb?l készült elixírek elfogyasztásával mérhetetlen er?knek parancsolnak. A Vashajó Szindikátust a véráldottak hatalma tette naggyá. Most azonban pusztító vihar k?zeleg: a sárkányok vérvonala gyengül?ben, a felemelked? Korvantin Birodalom pedig ugrásra készen várja a pillanatot, hogy kihasználhassa a Szindikátus gyengeségét. Ráadásul a vadonban is mozgolódás támad: a sárkányok támadásai egyre gyakoribbá válnak – és ami még ennél is rosszabb, szervezettnek t?nnek. Az utolsó reménysugár nem más, mint egy mitikus sárkány, amelynek nagyerej? vére valódi csodákra képes – ha egyáltalán létezik ez a rejtélyes lény. A sors végül három h?st választ ki magának. Claydon Tocreekre, a lajstromozatlan véráldottra és kisstíl? tolvajra hárul a feladat, hogy az ismeretlen vadonban felkutassa a legendás sárkányt, aminek a létezésében még csak nem is hisz. Lizanne Lethridge, a Szindikátus félelmetes erej?, ifjú elit kéme hirtelen találja magát ellenséges terepen, küldetése egyre veszedelmesebb helyzetekbe sodorja. Corrick Hilemore, az ismert világ peremén cirkáló kalózvadász Vashajó parancsnokhelyettese k?nnyen lehet, hogy túl nagy fába vágta a fejszéjét, amikor a k?ny?rtelen rablók nyomába eredt – és helyettük egy jóval komolyabb ellenséggel kerül szembe. Ahogy a birodalmak egymásnak feszülnek, mindhármuknak harcolni kell azért, amiben hisznek, ha nem akarják, hogy a világot elnyelje az ébred? t?z.

Mit ér az emlékezés, ha senki nem kíváncsi arra, ami elmúlt? B?n-e a hallgatás, ha védeni akarjuk szeretteinket a múlt sz?rny?ségeit?l? Mit tehetünk, ha a t?rténelem megismételni látszik ?nmagát?? Egy újságíró és egy sokat megélt nyolcvannégy éves h?lgy találkozása régi sebeket tép fel. Mélyen eltemetett emlékek kerülnek felszínre: A remény és a hit a kegyetlenséggel szemben, emberek az embertelenségben, és üzleti érdekek, melyek a pokol káoszát irányítják. Mi k?ti ?ssze egy kislány, egy náci tiszt, egy szovjet ezredes és egy m?fordító sorsát hetven év távlatából? ?Ez a t?rténet...
